Abstract: To provide 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 with a sensor includes a plurality of detection electrodes, a plurality of sensor wires, a plurality of pixels, a plurality of scanning lines, and a plurality of signal lines on a first insulating substrate. The detection electrodes are arrayed in a matrix (row-column configuration) in a first direction and a second direction. The sensor wires and the 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 in the first direction and superimposed on the respective slits of the two detection electrodes disposed side by side in the first direction.
