A display device includes a plurality of pixel electrodes; a bank having a plurality of openings respectively exposing a part of top surfaces of the plurality of pixel electrodes, a light emitting layer provided on the top surfaces of the plurality of pixel electrodes; and a common electrode covering the bank and the light emitting layer. Where an optical path of light emitted from any light emitting point in the light emitting layer and reflected by a corresponding pixel electrode, among the plurality of pixel electrodes, to return to the light emitting point is a first optical path, and an optical path of light emitted from the light emitting point and reflected by the corresponding pixel electrode to reach the bank is a second optical path, the second optical path has a length that is an integral multiple of a length of the first optical path.
