(54) Vertically aligned (VA) liquid-crystal display device


(57) A vertical-alignment-type liquid-crystal display device including a plurality of pixels has first and second substrates 16, 17 and a liquid-crystal layer 14 between them.
For domain regulation the first substrate, e.g. the CF substrate 16, includes first and second structures 20A and the second substrate 17 includes third and fourth structures 20B. The first and third structures extend in one direction in a pixel, while the second and fourth structures extend in a second direction, e.g. so as to form a zigzag, the first and second directions being different from the directions in which the edges of the pixel extend.
For improved grey-scale switching speed the third and fourth structures 20B are constituted in a plurality of linear portions each extending repetitively in the first and second directions in the pixel, but with an offset so that the distances d2', d2" between these portions and the first structures 20A are different from each other, when viewed in a direction perpendicular to the first substrate.
