Abstract: A display apparatus includes a substrate. A display element is disposed on the substrate. A first organic layer is disposed on the display element and includes a plurality of first organic patterns. The plurality of first organic patterns extends in a first direction and has reverse-graded sidewalls. A plurality of first light-shielding walls is disposed on sidewalls of the plurality of first organic patterns. A second organic layer is disposed on the first organic layer and includes a plurality of second organic patterns. The plurality of second organic patterns extends in the first direction and has sidewalls with alternating directions of inclination. A plurality of second light-shielding walls is disposed at sidewalls of the plurality of second organic patterns.
