Patent ID: 7705948

Claim:
A liquid crystal display device comprising: a substrate; an upper electrode layer formed on the substrate, the upper electrode layer having slits; an insulating layer formed between the substrate and the upper electrode layer; and a lower electrode layer formed between the substrate and the insulating layer; the slits allowing for application of a voltage between the upper electrode layer and the lower electrode layer, the voltage driving liquid crystal molecules, an upper electrode layer and a lower electrode layer formed on a same substrate via an insulating layer, the insulating layer comprising slits formed on the upper electrode layer for applying voltage between the upper electrode layer and the lower electrode layer and for driving liquid crystal molecules, edge portions of the slits each including a first curved portion the tangential direction of which at the edge portions with respect to a rubbing direction falls within a range from 0° to +90° and a second curved portion the tangential direction of which at the edge portions with respect to the rubbing direction falls within the range from 0° to −90°, where the direction toward an acute angle subtended by the long sides of the slits with respect to the rubbing direction is the positive direction, the second curved portion being smaller than the first curved portion, wherein the second curved portion includes a projecting portion, the projecting portion being located at a distal end of the second curved portion.
