Abstract: A display device includes: active stages each include a scan output circuit outputting a scan clock signal to a first output terminal and a carry output circuit outputting a carry clock signal to a second output terminal, when a voltage of a first node is at a logic high level. The scan output circuit and carry output circuit output a scan signal of a turn-off level to the first output terminal when a voltage of a second node or a carry signal is at a logic high level. An interval between pulses of the carry clock signal generated during one frame period is the same, and at least two of intervals between pulses of the scan clock signal generated during the one frame period are different from each other.

Abstract: A display device is provided. A display device including a plurality of light-output areas through which incident light is emitted and a light-blocking area which blocks the incident light, the display device includes a substrate, a bank layer which is disposed in the light-blocking area on the substrate and defines a plurality of openings, each of which is disposed in one of the plurality of light-output areas, and a color control pattern disposed in the opening of the bank layer, wherein the bank layer includes a first bank area which has a first thickness and defines the plurality of openings and a second bank area which is disposed between the plurality of openings and has a second thickness smaller than the first thickness.
