Abstract
A display device comprises a substrate provided with a first subpixel, a second subpixel, a third subpixel, and a fourth subpixel, a first electrode provided on the substrate, an organic light emitting layer arranged on the first electrode, and a second electrode arranged on the organic light emitting layer, wherein the organic light emitting layer includes a first organic light emitting layer and a second organic light emitting layer, the first organic light emitting layer and the second organic light emitting layer are arranged on the first subpixel, the second subpixel, and the fourth subpixel, only the second organic light emitting layer is arranged on the third subpixel, only the first organic light emitting layer emits light on the first subpixel and the second subpixel, only the second organic light emitting layer emits light on the third subpixel, and both of the first organic light emitting layer and the second light emitting layer emit light on the fourth subpixel. Since the organic light emitting layer may emit light in accordance with one-stack voltage even in case of a two-stack structure of the first subpixel and the second subpixel, overall power consumption may be reduced.
