A display device achieves a high resolution and a low power consumption through provision of subpixels each including a single light emitting layer and subpixels each including a plurality of overlapping light emitting layers. In the display device, it is also unnecessary to increase the number of expensive fine metal masks even for rendering of various grayscales. In addition, in the display device, different light emitting layers overlap with each other, and a charge generation layer is disposed between the overlapping light emitting layers, and, as such, emission of a secondary color can be achieved without necessity of a material for an additional light emitting layer of the secondary color.
