    Abstract: A display panel includes an upper display substrate including pixel areas arranged in each of pixel columns and a light blocking area and a lower display substrate including display elements respectively overlapping the pixel areas. The upper display substrate includes a base substrate, a color filter layer, and a light control layer including transmission portions overlapping first pixel areas arranged in a first pixel column and first conversion portions overlapping second pixel areas arranged in a second pixel column, and a barrier layer including first barriers disposed between the first conversion portions and the transmission portions and first sub-barriers disposed between adjacent first conversion portions. A first shortest distance from the base substrate to a lower surface of each of the first barriers is equal to a second shortest distance from the base substrate to a lower surface of each of the first sub-barriers.

    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 apparatus including a first sub-pixel, a second sub-pixel, and a third sub-pixel respectively representing different colors is provided. The apparatus includes an upper substrate, a functional layer disposed over the upper substrate and including a first quantum-dot layer and a second quantum-dot layer, and a color filter layer between the upper substrate and the functional layer and including a first color filter, a second color filter, and a third color filter. The first color filter corresponds to the first sub-pixel, the second color filter corresponds to the second sub-pixel, and the third color filter corresponds to the third sub-pixel. The first sub-pixel is a green sub-pixel, and a full width at half maximum of a transmission spectrum of the first color filter is in a range of about 45 nm to about 49 nm.
