Abstract: A display device includes: an array substrate; a counter substrate; a liquid crystal layer; and a light source that emits light into a side surface of the array substrate or a side surface of the counter substrate. The display device includes: first wiring lines in a first peripheral region outside a display region, the first wiring lines being configured to be supplied with a constant potential; and second wiring lines in a second peripheral region located opposite to the first peripheral region with the display region therebetween, the second wiring lines being coupled to the scanning lines. A shape of a region occupied by the first wiring lines in the first peripheral region is obtained by inverting a shape of a region occupied by the second wiring lines in the second peripheral region, in a mirror-symmetrical manner. The first wiring lines are not coupled to the scanning lines.
