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.

Abstract: A display device includes a display panel having a display area and a color filter layer including a black matrix and a color filter. Peripheral areas and a center area are in the display area. Light emitting areas and a non-light emitting area are in the display area. A center black matrix is in the non-light emitting area of the center area, and a peripheral black matrix is in the non-light emitting area of the peripheral area. Center color filters are in the light emitting areas of the center area, and peripheral color filters are in the light emitting areas of the peripheral area. First and second adjacent light emitting areas are in the peripheral area. First and second peripheral color filters are respectively in the first and second light emitting areas, and overlap each other in the non-light emitting area between the first and second light emitting areas.
