Abstract: An active element substrate and an opposed substrate sandwich a liquid crystal layer to constitute a liquid crystal display device. On the active element substrate, two signal lines respectively charge a pair of pixels that are adjacent to each other in a direction parallel to scanning lines. The two signal lines are provided intensively on a pixel electrode of one of the pair of pixels.

Abstract: The flexible wiring board has a first wiring film and a second wiring film. Because the first wiring film has a larger thickness than the second wiring film, the sectional area and electrical resistance of the first wiring film can be enlarged because of the larger film thickness even in a case where the first and second wiring films have almost the same width. Therefore, a high current can flow through the first wiring film, although the wiring film has a small width. As a result, a high density of the flexible wiring board can be easily achieved.
