Abstract: An organic electroluminescence display apparatus includes an insulating layer including a concave portion having a concave first upper surface, a first electrode including a curved electrode portion having a concave second upper surface overlapped with the concave portion, a pixel definition layer including a first opening defined therethrough to expose the second upper surface, an organic layer disposed on the first electrode, a second electrode disposed on the organic layer, and a light blocking layer including a second opening defined therethrough. The second opening has a width smaller than the first opening and overlaps with the first opening.

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.
