Patent ID: 7978298

Claim:
A liquid crystal display device comprising a first substrate, a second substrate provided so as to oppose the first substrate, and a vertical-alignment type liquid crystal layer provided between the first substrate and the second substrate; the liquid crystal display device having a plurality of pixels, each pixel including a first electrode formed on the first substrate, a second electrode formed on the second substrate, and the liquid crystal layer provided between the first electrode and the second electrode; the liquid crystal display device comprising wall-like structures regularly arranged on the liquid crystal layer side of the first substrate; and when a predetermined voltage is applied, the liquid crystal layer forming at least one liquid crystal domain that takes a radially-inclined orientation state in a region substantially surrounded by the wall-like structures, wherein, the wall-like structures appear as linear structures that substantially surround the at least one liquid crystal domain when viewed from a substrate normal direction, the second substrate includes a protrusion projecting toward the liquid crystal layer in a region corresponding to the liquid crystal domain; the liquid crystal layer contains a chiral agent; and a thickness d LC of the liquid crystal layer, a natural chiral pitch p of the liquid crystal layer, and a distance d RW from a center of the protrusion to the wall-like structure satisfy the relationships d RW >p and d LC /p≧0.15.
