Abstract: A display device includes a display panel and an anti-reflection unit directly disposed on the display panel. The display panel includes first to third light emitting elements, each of which includes first and second electrodes, and a light emitting layer, which is disposed between the first electrode and the second electrode. The pixel definition layer includes a first portion, in which a light-emitting opening exposing the first electrode is defined, and a second portion, which is disposed on and overlapped with the first portion. The anti-reflection unit includes first to third color filters overlapped with the first to third light emitting elements, respectively, and a color spacer, which is overlapped with the second portion and is thicker than each of the first to third color filters.
