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 display device includes: a pixel defining layer defining openings arranged in first and second directions, the openings forming emission areas in which light emitting elements are disposed to emit light of different colors; a light blocking layer disposed on the pixel defining layer, and defining holes, each overlapping the opening and having a larger diameter than the opening; and color filters disposed on the light blocking layer to overlap the holes and overlap the emission areas. The opening has an opening interval, which is defined as a difference in diameter between the overlapping hole and the opening, in the openings, among homogeneous openings in which the light emitting elements for emitting light of the same color are disposed, the homogeneous openings adjacent in the first or second direction have different opening intervals, and among the homogeneous openings, openings having different opening intervals are at least three types.

Abstract: A display device includes an organic layer, an anode, a pixel defining layer, a cathode, a light emitting layer, a light blocking layer, a color filter, and a sensing electrode. The organic layer includes an anode-connecting opening. The anode is disposed on the organic layer and is partially disposed inside the anode-connecting opening. The pixel defining layer includes an anode-exposing opening that exposes the anode. The cathode overlaps the anode. The light emitting layer is between the anode and the cathode. The light blocking layer overlaps the cathode and includes a blocking layer opening. The color filter fills the blocking layer opening. The sensing electrode is at least partially covered by the light blocking layer. The anode-connecting opening overlaps with each of the sensing electrode, the pixel defining layer, and the light blocking layer in a plan view of the display device.
