Abstract: In the second area, the lower base surface of the wirings is in contact with the first inorganic insulating film including a stepped portion including upper surfaces having mutually different heights and being adjacent to each other in the second direction, and a stepped surface rising from the upper surfaces except the uppermost surface. The first inorganic insulating film constitutes at least the upper surfaces except the lowest surface, and the stepped surface. The adjacent wirings include a pair of convex portions protruding toward a direction facing each other. One and the other of the pair of convex portions are separated to face each other at a position where the stepped portion does not exist in the second area in the first inorganic insulating film.
