Abstract: A display device includes a display panel including an antireflection layer on a light emitting element layer which includes a first pixel defining layer in which an opening defining a light emitting area of a first pixel is defined, and a second pixel defining layer in which an opening defining a light emitting area of a second pixel is defined. The antireflection layer includes first and second light blocking layers respectively overlapping the first and second pixel defining layers, and includes a first gap defined by a length of a predetermined direction from an edge of the opening to an edge of an opening of the first light blocking layer, and a second gap defined by a length from an edge of the opening to an edge of an opening of the second light blocking layer in the predetermined direction. The first gap is less than the second gap.

Abstract: An organic light emitting diode display includes: a substrate; an overlapping layer on the substrate; a pixel on the substrate and the overlapping layer; and a scan line, a data line, a driving voltage line, and an initialization voltage line that are connected to the pixel. The pixel includes: an organic light emitting diode; a second transistor connected to the scan line and the data line; a driving transistor including a gate electrode, an input terminal, and an output terminal, and to apply a current to the organic light emitting diode from the output terminal; and a voltage application transistor to apply a voltage to the overlapping layer. An output of the second transistor is connected to the input terminal of the driving transistor, and the overlapping layer is between the driving transistor and the substrate while overlapping with the driving transistor on a plane.
