摘要:
In a liquid crystal display device which presents display by forming liquid crystal domains that take radially-inclined orientation, persisting display unevenness is prevented from occurring when the panel surface is pressed, thus realizing high-quality displaying.A liquid crystal display device according to the present invention includes a first substrate, a second substrate provided so as to oppose the first substrate, and a vertical-alignment type liquid crystal layer provided therebetween. The liquid crystal display device according to the present invention further includes wall-like structures regularly arranged on the liquid crystal layer side of the first substrate, such that, when a predetermined voltage is applied, the liquid crystal layer forms at least one liquid crystal domain that takes a radially-inclined orientation state in a region substantia y surrounded by the wall-like structures. The second substrate includes a protrusion projecting toward the liquid crystal layer in a region corresponding to the liquid crystal domain, and the liquid crystal layer contains a chiral agent. The thickness dLC of the liquid crystal layer, the natural chiral pitch p of the liquid crystal layer, and the distance dRW from the center of the protrusion to the wall-like structure satisfy the relationships dRW>p and dLC/p≧0.15.
