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.
