PROBLEM TO BE SOLVED: To solve the problem for example, that recently the width of seal lines are becoming narrower because of the demand for making a trim narrower has increased, so seal adhesion strength has become lower.SOLUTION: One or more grooves are formed on a resin layer which is a ground of a seal area. A formation direction (side surface) of the grooves is preferably a vertical direction of external stress. On a seal straight line area, in addition to grooves in a parallel direction of the seal, grooves are formed in a vertical direction of the seal, preferably. In addition, on a seal angle area, grooves are formed so as to draw a salient-shaped curve in a direction going toward a display area (active area), preferably. |
