Abstract
According to one embodiment, a display device includes a display region where pixels are arranged. Each of the pixels includes a pixel electrode, a light emitting element, a drive transistor, a first capacitance electrode layer opposed to the pixel electrode and held at a constant potential, and an insulating layer forming an auxiliary capacitance together with the pixel electrode and the first capacitance electrode layer. A value of the auxiliary capacitance of the first pixel, of the values of the auxiliary capacitance of the pixels is the largest.
