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 liquid crystal display device includes a first row including first, second, and third first-color pixels; a second row including fourth, fifth, and sixth first-color pixels; and a third row including seventh, eighth, and ninth first-color pixels. The first, fourth, and seventh first-color pixels are aligned. The second, fifth, and eighth first-color pixels are aligned. The third, sixth, and ninth first-color pixels are aligned. The second first-color pixel is disposed between the first and third first-color pixels. Each pixel electrode of the first, third, fifth, seventh, and ninth first-color pixels may receive a high voltage for a gray level. Each pixel electrode of the second, fourth, sixth, and eighth first-color pixels may receive a low voltage for a gray level lower than the high voltage for a gray level. Liquid crystal molecules in each pixel have two domain directions.
