    Abstract: A display apparatus for providing an image through an array of a plurality of pixels includes: an optical panel which converts light of the light-emitting panel into light of another color or transmit the light of the light-emitting panel. The optical panel includes: a substrate; a plurality of color filters arranged over the substrate; a first light-blocking layer arranged in the non-pixel area; a second light-blocking layer arranged in the non-pixel area and on the first light-blocking layer; and a color-converting layer and a transmission layer each overlapping a corresponding color filter from among the plurality of color filters in a plan view. Each of the first light-blocking layer and the second light-blocking layer defines a plurality of holes corresponding to the plurality of pixels, and a width of a hole of the second light-blocking layer is greater than a width of a hole of the first light-blocking layer.

    Abstract: A display panel includes a base substrate including: a plurality of pixel regions and a peripheral region adjacent thereto; a pixel defining film disposed on the base substrate and having a plurality of openings, each of which corresponding to a respective one of the plurality of pixel regions; a plurality of light emitting elements disposed on the base substrate corresponding to the plurality of openings and configured to generate first color light; an encapsulation member disposed on the plurality of light emitting elements; a light shield pattern disposed on the encapsulation member and overlapping the peripheral region when viewed in a plan view; and a light control layer disposed on the encapsulation member and the light shield pattern and overlapping the plurality of pixel regions. The pixel defining film includes a first color material, and the light shield pattern includes a second color material different from the first color.
