Abstract:
A display device includes an electroluminescent layer laminated on pixel electrodes and a multifunctional electrode and a common electrode laminated on the electroluminescent layer. The electroluminescent layer includes a lower common layer that continuously overlaps and contacts the pixel electrodes and the multifunctional electrode and light emitting layers separated from each other corresponding to each of the pixel electrodes on the lower common layer. The multifunctional electrode includes portions each passing between a pair of adjacent pixel electrodes of the pixel electrodes, and is set to a potential closer to that of the common electrode than the pixel electrodes in an image display period, and at least a part of the multifunctional electrode functions as at least one electrode group of a transmission electrode group and a reception electrode group in a touch sensing period.
