- the conductive portion 124 has a configuration in which the third layer 200, the first layer 210, and the second layer 220 are stacked in this order.
- the first layer 210 is made of, for example, a metal such as Al or an Al alloy, and the second layer 220 and the third layer 200 are conductive materials having higher hardness and lower etching rate than the first layer 210, such as Mo. Or it is formed with Mo alloy.

- the first layer 210 is made of an AlNd alloy

- the thickness of the first layer 210 is, for example, not less than 50 nm and not more than 1000 nm. Preferably it is 100 nm or less.
- the second layer 220 is thinner than the first layer 210.
- the thickness of the second layer 220 is, for example, 30 nm or less, preferably 25 nm or less.
- the upper surface of the end portion 222 of the second layer 220 is inclined. Specifically, since the width of the first layer 210 is narrower than the width of the second layer 220, the first layer 210 is not located below the end portion 222 of the second layer 220. Then, the end portion 222 of the second layer 220 is bent starting from a portion overlapping with the end of the first layer 210.
- the width of the end portion 222 (that is, the width of the bent portion) is, for example, 400 nm or more.
- the angle ⁇ of the upper surface of the end portion 222 with respect to the first surface 112 is, for example, 5 ° or more and 20 ° or less.
- a gap 224 is formed below the surface of the end portion 222 on the first surface 112 side. Specifically, since the width of the third layer 200 is wider than the width of the first layer 210, the gap 224 is located between the end portion 222 and the third layer 200.
- the first electrode 120 covers a part of the first surface 112 and the conductive portion 124, and is bent at the boundary between the first surface 112 and the conductive portion 124.
- the upper surface of the end portion of the conductive portion 124 that is, the upper surface of the end portion 222 of the second layer 220 is inclined in a direction approaching the first surface 112. Accordingly, the bending angle of the first electrode 120 at the boundary between the first surface 112 and the conductive portion 124 becomes small. As a result, the first electrode 120 is continuously formed at this boundary. Details will be described below.
- FIG. 2 is a cross-sectional view showing a method for manufacturing the optical device 100.
- the third layer 200, the first layer 210, and the second layer 220 are formed in this order on the substrate 110.
- Each of these layers is formed using, for example, a sputtering method.
- the substrate 110 is a resin substrate
- an inorganic barrier film such as SiN x or SiON is formed on the substrate 110 for moisture prevention
- the third layer 200 is formed on the inorganic barrier film (not shown). )
- a resist pattern (not shown) is formed on the second layer 220, and the second layer 220, the first layer 210, and the third layer 200 are formed using the resist pattern as a mask. Is etched (for example, wet etching). Thereby, the conductive part 124 is formed. Note that, under this etching condition, the etching rate of the first layer 210 is faster than the etching rates of the third layer 200 and the second layer 220. For this reason, the first layer 210 is etched faster than the third layer 200 and the second layer 220.
- the side surface of the first layer 210 enters the center side of the conductive portion 124 rather than the side surfaces of the second layer 220 and the third layer 200, and the first layer 210 is below the end of the second layer 220.
- the distance d between the side surface of the first layer 210 and the side surface of the second layer 220 is preferably 400 nm or more, for example.
- the size of the interval d is controlled by adjusting etching conditions (for example, etching time).
- the end 222 of the second layer 220 may be bent toward the first surface 112 of the substrate 110 or may not be bent.
- the first electrode 120 is formed on the substrate 110 and the conductive portion 124 by using, for example, a sputtering method.
- the first electrode 120 is formed on the conductive portion 124, whereby the end portion 222 of the second layer 220. Is bent toward the first surface 112 of the substrate 110. And since the bending angle of the 1st electrode 120 in the boundary of the 1st surface 112 and the electroconductive part 124 becomes small, the 1st electrode 120 is continuously formed in this boundary.
- the upper surface of the end portion 222 of the second layer 220 of the conductive portion 124 is inclined toward the first surface 112 of the substrate 110.
- the bending angle of the first electrode 120 at the boundary between the first surface 112 and the conductive portion 124 becomes small. Accordingly, the first electrode 120 is continuously formed at this boundary. As a result, the resistance of the first electrode 120 can be suppressed from increasing at the boundary between the conductive portion 124 and the first surface 112.
- the angle ⁇ of the upper surface of the end portion 222 with respect to the first surface 112 is 5 ° or more and 20 ° or less, the bending angle of the first electrode 120 at the boundary between the first surface 112 and the conductive portion 124 is further reduced.
- the resistance of the first electrode 120 at the boundary between the conductive portion 124 and the first surface 112 is further unlikely to increase.
- the width of the end portion 222 is 400 nm or more, for the same reason, the resistance of the first electrode 120 at the boundary between the conductive portion 124 and the first surface 112 is hardly further increased.
- the etching rate of the first layer 210 is higher than the etching rate of the second layer 220. Therefore, by positioning the side surface of the first layer 210 inside the side surface of the second layer 220, the end portion 222 of the second layer 220 can be projected from the first layer 210. In this case, the upper surface of the end portion 222 can be easily inclined toward the first surface 112 of the substrate 110 by bending the end portion 222 with the side surface (end) of the first layer 210 as a starting point.
- FIG. 3 is a view in which the functional layer 130 is removed from FIG.
- the optical device 100 shown in the figure is a light emitting device and is used as an illumination device.
- the optical device 100 is a polygon such as a rectangle, for example, and has an organic EL element 102 (shown in FIG. 5), a first terminal 150, and a second terminal 160.
- the organic EL element 102 forms a light emitting region of the optical device 100. Note that the layout of each component of the optical device 100 described below is merely an example.
- the organic EL element 102 has a configuration in which a first electrode 120, a functional layer 130, and a second electrode 140 are stacked on a substrate 110. Since the first electrode 120 is a transparent electrode, the light emitted from the organic EL element 102 is emitted to the outside through the first electrode 120.
- the first electrode 120 is an anode of the organic EL element 102 and is connected to the first terminal 150 as shown in FIG.

- a layer similar to the conductive portion 124 may be formed between the first terminal 150 and the substrate 110 and between the second terminal 160 and the substrate 110. In this case, the resistance of the first terminal 150 and the second terminal 160 can be lowered.
- FIG. 6 is a diagram illustrating a state in which the optical device 100 is bent when a flexible substrate is used as the substrate 110.
- the substrate 110 is a resin substrate
- an inorganic barrier film 114 such as SiN x or SiON is provided on the first surface 112 of the substrate 110 or both surfaces of the first surface 112 and the opposite surface to prevent moisture. Is formed.
- the optical device 100 (that is, the substrate 110) is curved in a direction intersecting the conductive portion 124, for example, a direction orthogonal to the conductive portion 124 (x direction in FIG. 3).
- a force in the bending direction is applied to the stacked structure of the first electrode 120, the functional layer 130, and the second electrode 140.
- the region located at the boundary between the substrate 110 and the conductive portion 124 in the first electrode 120 is discontinuous, there is a possibility that the first electrode 120 may crack starting from the discontinuous portion. Come out.
- the region located at the boundary between the substrate 110 and the conductive portion 124 in the first electrode 120 is also continuous. Therefore, even if the optical device 100 is curved, the first electrode 120 can be prevented from cracking.
