  • Patent number: 8427610
    Abstract: A liquid crystal display device includes a pair of substrates provided opposite to each other, a common electrode provided on one of the pair of substrates, and a pixel electrode provided on the other of the pair of substrates. A vertical alignment type liquid crystal is sealed between the pair of substrates. An alignment film is polymerizable upon irradiation of UV, and is obtained by polymerizing substantially the entire alignment film with a voltage applied between the electrodes after the liquid crystal is sealed between the substrates. A pixel region has areas whose electro-optical characteristics are different from each other because of a difference between applied voltages at the time of polymerization.

  • Patent number: RE43640
    Abstract: The invention relates to a liquid crystal display device used for a display part of an information equipment and a driving method thereof, and has an object to provide a liquid crystal display device in which excellent viewing angle characteristics can be obtained and a driving method thereof. When a relatively high level data voltage is applied to a gate electrode of a TFT, a driving voltage is applied to a liquid crystal layer for a long time and a white display is realized. When a relatively low level data voltage is applied to the gate electrode of the TFT, the driving voltage is not applied to the liquid crystal layer, and a black display is realized. When an intermediate data voltage between the high level and the low level is applied to the gate electrode of the TFT, the TFT keeps an on state for a time determined by a time constant depending on a capacitance and a resistance. The driving voltage is applied to the liquid crystal layer for the on time.
