Patent ID: 7292301

Claim:
A liquid crystal display device having a plurality of pixels each having a first electrode, a second electrode facing the first electrode, and a vertical alignment liquid crystal layer placed between the first and second electrodes, the device comprising: first alignment regulating means having a first width located at the first electrode side of the liquid crystal layer; second alignment regulating means having a second width located at the second electrode side of the liquid crystal layer; a liquid crystal region having a third width defined between the first alignment regulating means and the second alignment regulating means, wherein the third width is in a range between 2 μm and 14 μm, and wherein at least one of the regulating means comprises at least one slit in at least one of the electrodes, and wherein a ratio of the third width (W 3 ) to a width of the slit (SW) is W 3 /SW <1.5, and a ratio of SW/d>=3, where d is a thickness of the liquid crystal layer.
