In order to arrange the positions of the silver paste points reasonably, the inventor conducts the following research on a display panel in the prior art:
fig. 1 is a schematic top view of a display panel according to the prior art, and fig. 2 is a schematic cross-sectional view of the display panel according to the prior art, wherein fig. 2 is a cross-sectional view taken along a cut line S '-S' in fig. 1, and as shown in fig. 1 and 2, the display panel includes a first substrate 10 'and a second substrate 20' opposite to each other, a display material layer 30 'between the first substrate 10' and the second substrate 20', and a polarizer 40' on a side of the second substrate 20 'away from the first substrate 10'. In the first direction a ', the length of the first substrate 10' is greater than the length of the second substrate 20' to form a stepped region TA ' on the first substrate 10 '. The display panel further includes a silver paste point P ', which extends from the position of the step area TA' of the first substrate 10 'to the second substrate 20', so as to realize electrical conduction between the first substrate 10 'and the second substrate 20', thereby releasing the static electricity on the first substrate 10 'through the second substrate 20', and releasing the static electricity on the second substrate 20 'through the first substrate 10'.
Meanwhile, the display panel has a display area AA ' and a non-display area BA ' surrounding the display area AA ', and the screen occupation ratio of the existing display requirements is continuously increased, so that the non-display area BA ' is continuously reduced, and the distance C ' between one side of the step area, that is, the edge of the second substrate 20' and the edge of the display area AA ' is reduced. And the distance C ' is composed of a distance a ' between the edge of the display area AA ' and the edge of the polarizer 40' and a distance B ' between the edge of the polarizer 40' and the edge of the second substrate 20 '. For the distance a ', when the distance a' is too small, the edge of the polarizer 40 'is visible in the display area AA' after the polarizer 40 'is easily attached based on the attachment error of the polarizer 40'; for the distance B ', the distance B' needs to ensure enough space for placing the silver paste point P ', and when the distance B' is too small, the silver paste point P may not be placed.

With respect to embodiments of the display panel and the display device provided by the present invention, the following will be described in detail.
Fig. 3 is a schematic top view of a display panel according to an embodiment of the present invention, and fig. 4 and 5 are schematic cross-sectional views of the display panel according to the embodiment of the present invention, wherein fig. 4 is a cross-sectional view taken along a tangent line S1-S1 in fig. 3, and fig. 5 is a cross-sectional view taken along a tangent line S2-S2 in fig. 3, and in an embodiment, as shown in fig. 3 to 5, the display panel has a display area AA including a first edge a1 and a second edge a2 opposite in a first direction a, and a third edge A3 and a fourth edge a4 opposite in a second direction b, wherein the first edge a1 and the third edge A3 are connected by a first corner edge R1, that is, the display area AA has a corner design, and is at least arranged at a position where the first edge a1 and the third edge A3 intersect, and the edge of the display area AA is a first corner R1, wherein the first corner edge R1 may be a straight line, an arc line, or other regular and irregular line, the first direction a and the second direction b intersect, optionally, the first direction a and the second direction b are perpendicular.
The display panel includes: the display panel comprises a first substrate 10, a second substrate 20 arranged opposite to the first substrate 10 in a third direction c, a display material layer 30 arranged between the first substrate 10 and the second substrate 20, a polarizer 40 arranged on one side of the second substrate 20 far away from the first substrate 10, and a silver glue point P for conducting the first substrate 10 and the second substrate 20, wherein electrostatic discharge of the first substrate 10 and the second substrate 20 is realized through the silver glue point P, and the third direction c is perpendicular to the first direction a and the second direction b. The display material layer 30 may be a liquid crystal material.
