According to one embodiment, a display device includes first, second, and third interconnects, switch elements, pixel electrodes, a display layer, and a controller. The switch elements are arranged in a matrix configuration, and connected to the first and second interconnects. The pixel electrodes are electrically connected to the switch elements. The third interconnects oppose the pixel electrodes. The display layer is provided on the pixel electrodes. The controller is electrically connected to the first, second, and third interconnects. The second interconnects include a first color interconnect. The controller performs a first operation of sequentially selecting the first interconnects and supplying a first color image signal to the first color interconnect. The controller performs a second operation of sequentially selecting the first interconnects and supplying a second color image signal to the first color interconnect. The controller performs a third operation being different from the first and second operations.
