Abstract: A display device includes sub-pixels. The first and third sub-pixels overlap in a first direction. The second sub-pixel is spaced from the first and third sub-pixels in a second direction. Each of the sub-pixels includes a pixel-circuit layer including a pixel circuit including first and second transistors, a data line, and a scan line, and a light-emitting-element layer on the pixel-circuit layer and including a light emitting element. The pixel circuit includes first to third pixel circuits in the first to third sub-pixels, respectively. The data line includes first to third data lines included in the first to third sub-pixels, respectively, and electrically connected to the first to third pixel circuits, respectively. The first to third data lines are adjacent. The second data line is not between the first and third data lines such that only one side of the second data line faces the first and third data lines.

Abstract: A scan driver for a display device includes a plurality of stages outputting scan signals. A first stage of the plurality of stages includes first to sixth transistors connected to a first carry clock line, a carry line, a previous carry line, and a second carry clock line. In a first frame period, the second carry clock line is configured to receive a second carry clock signal having at least one pulse with substantially the same phase as at least one of first pulses of a first carry clock signal to be applied to the first carry clock line.
