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.
1. A vertical alignment type liquid crystal display device including a plurality of pixels, comprising: a first substrate and a second substrate; and a liquid crystallayer between the first substrate and the second substrate; wherein 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, thealignment 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, distances betweenthe first and second linear portions and an adjacent alignment control structure of the second substrate being different from each other, and each of the first and second linear portions and the alignment control structures of the second substrate arearranged in parallel.
2. The liquid crystal display device according to claim 1, wherein when viewed in the direction, the alignment control structures of the second substrate include adjacent two alignment control structures between which the first and secondlinear portions are arranged, a distance between the first linear portion and one of the two alignment control structures and a distance between the first linear portion and the other of the two alignment control structures are different from each other,and a distance between the second linear portion and the one of the two alignment control structures and a distance between the second linear portion and the other of the two alignment control structures are different from each other.
3. The liquid crystal display device according to claim 1 or 2, wherein when a voltage is applied to the liquid crystal layer, liquid crystals are aligned by the alignment control structures in a direction perpendicular to directions in whichthe first and second linear portions and the alignment control structures of the second substrate extend.
