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 display device includes pixels, scanning lines, signal lines on a first insulating substrate, detection electrodes arrayed in a matrix in first and second directions, and sensor wires and signal lines 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 disposed side by side in the first direction and superimposed on the respective slits of the two detection electrodes.

Abstract: According to one embodiment, a display device includes a first substrate, a second substrate, a liquid crystal layer including polymers and liquid crystal molecules, and a light-emitting element. The first substrate includes a transparent substrate, a scanning line, a signal line crossing the scanning line, a switching element electrically connected to the scanning line and the signal line, an organic insulating film overlapping the switching element, and a pixel electrode electrically connected to the switching element. A thickness of the organic insulating film located between the transparent substrate and the pixel electrode is less than a thickness of the organic insulating film overlapping the switching element.

Abstract: A display device includes: an array substrate including a plurality of first light-transmitting electrodes each disposed in a corresponding one of pixels; a counter substrate including positions overlapping the first light-transmitting electrodes and provided with a second light-transmitting electrode; a liquid crystal layer including polymer-dispersed liquid crystals filled between the array substrate and the counter substrate; and at least one light source configured to emit light toward a side surface of the counter substrate. The array substrate includes, in each of the pixels, a third light-transmitting electrode that at least partially overlaps the first light-transmitting electrode in the plan view with an insulating layer interposed therebetween. An area of the third light-transmitting electrode in the pixel in a display region closer to the light source is larger than an area of the third light-transmitting electrode in the pixel in a display region farther from the light source.
