摘要： 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.

摘要： 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. By this, a half tone display is realized according to the ratio of the on time of the TFT in one frame period.

摘要： A liquid crystal display including two substrates, gate bus lines, liquid crystal molecules, and a polymer that determines directions in which the liquid crystal molecules tilt. A plurality of divisional areas are arranged on one of the substrates. The pixels are aligned in a column between drain bus lines. A pixel electrode is formed at each of the divisional areas. A first thin film transistor drives a first divisional area, and a second thin film transistor drives a second divisional area of the same column. The first and second thin film transistors are electrically connected to the same gate bus line. Either the pixel electrodes formed at each of the divisional areas are electrically insulated from each other, or they are connected to each other through a high resistance. A first threshold voltage within the first divisional area is different from a second threshold voltage of the second divisional area.
