Abstract:
1. A flat display provided with an array substrate having an upper side and a lower side, the array substrate comprising: signal lines and scanning lines longitudinally and transversely arranged on an insulating substrate; a plurality of pixel electrodes connected to respective intersections of said signal lines and said scanning lines via switching elements; a plurality of auxiliary capacity electrodes electrically connected to said switching elements; and an auxiliary capacity feeder disposed opposite to said auxiliary capacity electrode via an insulating layer, said flat display comprising: a first wiring layer electrically connected to said auxiliary capacity electrode; a second wiring layer electrically connected to source electrodes of said switching elements and said first wiring layer; and a third wiring layer electrically connected to said pixel electrode and the source electrodes of said switching elements, wherein said first wiring layer is formed on a layer closer to the lower side of the array substrate than the second wiring layer and the second wiring layer is formed on a layer closer to the upper side of the array substrate than the first wiring layer, and a length of said first wiring layer is set to be equal to that of the second wiring layer.
