Abstract: A display device with a sensor in which the deterioration of display quality is suppressed even when the sensor wires are superimposed on the respective slits of two detection electrodes disposed side by side. The device includes a plurality of detection electrodes, sensor wires, pixels, scanning lines, and signal lines on a first insulating substrate. The detection electrodes are arrayed in a matrix in first direction and second directions. The sensor wires and signal lines are disposed alternately in the first direction and provided on the same layer. Switching elements of two of the pixels disposed side by side in the first direction each are coupled to one of the signal lines, and the signal line is superimposed on the corresponding detection electrode that straddles the two pixels. The sensor wires are disposed between the two pixels and superimposed on the respective slits of the two detection electrodes.

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.
