Patent ID: 8619228

Claim:
A liquid crystal display device, comprising an array substrate and a counter substrate that face each other with a liquid crystal layer therebetween, wherein the array substrate includes: a first electrode having a comb-teeth shape and being electrically connected with an active element; a second electrode having a comb-teeth shape, facing the first electrode with an insulating layer therebetween, and including a protruding portion protruding from the first electrode in a direction where comb teeth are arranged; and an alignment sustaining layer formed above a surface of the array substrate being in contact with the liquid crystal layer and giving liquid crystals a pre-tilt to a direction in which the second electrode protrudes from the first electrode, in a direction in which the comb teeth are arranged, and wherein the counter substrate includes a third electrode with a voltage being applied between the third electrode and the first electrode during liquid crystal driving.
