Title: Vertically-alligned (VA) liquid crystal display device

Abstract: A vertical alignment type liquid crystal display device including a plurality of pixels, which further includes a first substrate and a second substrate and a liquid crystal layer between the first substrate and the second substrate. The first substrate and the second substrate include alignment control structures which extend linearly, and when viewed in a direction vertical to the first substrate, in a pixel, the alignment control structure of the first substrate and the alignment control structures of the second substrate are arranged alternately. The alignment control structure of the first substrate includes first and second linear portions, and distances between the first and second linear portions and an adjacent alignment control structure of the second substrate are different from each other. Additionally, each of the first and second linear portions and the alignment control structures of the second substrate are arranged in parallel.
