Abstract: If a divided area of common electrode layers is positioned on a source line, a leakage electric field on the source line has an effect on a liquid crystal layer through the divided area of the common electrode layers. A display device includes an array substrate and a counter substrate. The array substrate includes scanning signal wiring layers, video signal wiring layers, pixel electrode layers arranged in a layer higher than the video signal wiring layers, and common electrode layers arranged in a layer higher than the pixel electrode layers. The common electrode layers are arranged in positions covering the video signal wiring layers in a plan view. The common electrode layers are divided in the extending direction of the video signal line.
