Abstract: A display device includes: an array substrate; a counter substrate; a liquid crystal layer between the array substrate and the counter substrate; spacers regulating a distance between the array substrate and the counter substrate; and a light source. The array substrate includes: signal lines arranged in a first direction; scan lines arranged in a second direction; switching elements each of which is coupled to a corresponding scan line and a corresponding signal line; and an organic insulating layer covering at least the switching elements. An area surrounded by the scan lines and the signal lines has a second area having a thickness less than that of the organic insulating layer in a first area overlapping the switching elements, the scan lines, and the signal lines in plan view. The spacers arranged in the first area have a thickness less than that of the organic insulating layer in the first area.

Abstract: A display device with a sensor in which deterioration of display quality is suppressed even when sensor wires are superimposed on respective slits of detection electrodes disposed side by side. The display device includes 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 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 disposed side by side and superimposed on the respective slits of the two detection electrodes disposed side by side.
