Abstract: Recently, with an increasing demand for narrowing a frame, the seal line width is inclined to get finer, which deteriorates the seal adhesive strength. One or a plurality of grooves are formed in a resin layer that is a foundation of a seal area. A direction of forming a groove (lateral surface) is preferably in a vertical direction to the external stress. In a seal straight portion, a groove is preferably formed not only in a parallel direction to the seal but also in the vertical direction. In a seal corner portion, a groove is preferably formed in a shape curved convexly toward a direction of a display area (active area).
