    Abstract: A display device comprises pixel electrodes disposed on a substrate and spaced apart from one another, a pixel-defining film disposed on the substrate and including openings, which are spaced apart from one another and overlap the pixel electrodes, organic light-emitting layers disposed in the openings of the pixel-defining film, a common electrode disposed between the pixel-defining film and the organic light-emitting layers, an encapsulation layer disposed on the common electrode, a light-blocking layer disposed on the encapsulation layer and including holes, which overlap the openings and are spaced apart from one another, and color filters disposed in the holes of the light-blocking layer and overlapping the openings. Sides of each of the openings have concave-convex patterns including convex portions that protrude outwardly and concave portions that are inwardly depressed. The color filters are disposed to partially overlap one another on the light-blocking layer.

    Abstract: A light emitting display device includes a substrate, an organic layer, a conductor, an anode, and a pixel definition layer. The organic layer overlaps the substrate and has a connection opening. The conductor is positioned between the substrate and the organic layer. The anode is positioned on the organic layer and is partially positioned inside the connection opening. The pixel definition layer exposes an exposed portion of the anode. The organic layer has a halftone exposure portion and a neighboring portion. The halftone exposure portion overlaps the exposed portion of the anode and overlaps the conductor. The neighboring portion neighbors the halftone exposure portion. A face of the halftone exposure portion and a face of the neighboring portion are spaced from the substrate by a first distance and a second distance, respectively. A difference between the first distance and the second distance is 30 nm or less.
