Abstract: A display device includes at least a first luminance range and a second luminance range which includes a luminance different from the first luminance range. In a boundary area of a second dimming range corresponding to the second luminance range and which is adjacent to a first dimming range corresponding to the first luminance range, a reference luminance emitted from a pixel is maintained as a first constant luminance value, and an off-duty number, which is the number of periods in which the pixel is turned off during one frame, is gradually increased by an emission control signal.

Abstract: A display device includes: a substrate; a pixel defining layer disposed on the substrate and that includes a pixel opening; an emission layer that overlaps the pixel opening of the pixel defining layer; and an anti-reflection layer that overlaps the pixel defining layer along a direction perpendicular to a surface of the substrate and is disposed along a portion of an edge of the pixel opening.
