ABSTRACT:
Liquid crystal 20 is sealed between a first substrate 10 and a second substrate 16 opposed each other. A first electrode 12 is formed on the first substrate 10 at a prescribed position in a prescribed region. A second electrode 18 is formed on the second substrate 16 at a position offset with respect to the first electrode 12 in the prescribed region. When a voltage is applied between the first and second electrodes 12 and 18, the prescribed region is divided in at least two regions of a first region and a second region where application of the voltage to the liquid crystal 20 is different between the two regions. Orientations of the liquid crystal 20 in the first region and that in the second region are different from each other. As a result, a view angle which is equal or larger than that obtained by in-plane switching can be obtained. The first electrode 12 and the second electrode 18 are formed on the substrates 10, 16, which are different from each other, whereby it is not necessary to consider short-circuit between the adjacent electrodes 12, 18. The liquid crystal display device having a large view angle can be fabricated with high yields.
