SOLUTION: After a sealant is injected from a dispenser to form a plurality of seal patterns 2 having liquid crystal injection ports 2a on a transparent electrode substrate 1 like a matrix, a pixel substrate 4 is stuck to the transparent electrode substrate 1 with seal patterns 2 interposed between them. Then the pattern they are divided in the direction in which liquid crystal injection ports 2a are exposed to manufacture a liquid crystal display element bar 8. A liquid crystal layer 6 is injected through liquid crystal injection ports 2a of the liquid crystal display element bar 8, and the liquid crystal display element bar 8 is divided in a direction which is different from the direction in which liquid crystal injection ports 3a are exposed to manufacture a liquid crystal display element 5. In this manufacturing method, the seal patterns 2 are drawn by using the sealant from one end to the other on the transparent electrode substrate 1 with a position which is a prescribed length apart from a liquid crystal injection port 2a as the start point by one stroke so that they may be connected to each other.

As shown in FIG. 1, instead of the (ultraviolet-curable seal pattern forming step) in the conventional method of manufacturing a liquid crystal display element,
An ultraviolet-curable sealant is injected from a dispenser (not shown), and a position P, which is a predetermined distance away from the liquid crystal injection port 2a, is used as a starting point, and one stroke is drawn from one end to the other end on the transparent electrode substrate 1. Then, an ultraviolet-curable seal pattern line 3 in which a plurality of ultraviolet-curable seal patterns 2 are connected is formed. Next, similarly, the ultraviolet-curable seal pattern lines 3 are sequentially formed at a predetermined pitch in a direction orthogonal to the direction in which the ultraviolet-curable seal pattern lines 3 are formed.

By doing so, the injection amount of the ultraviolet-curable sealant emitted from the dispenser is unstable at the start of injection, but is stable after the start, so that the application start position is set at the liquid crystal injection position. Since the starting point is the position P which is separated from the inlet 2a by a predetermined length, the application of the ultraviolet-curable sealant is stable before reaching the liquid crystal inlet 2a. Therefore, it is possible to prevent the liquid crystal injection port 2a from being closed or from being partially dropped.
