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.
