摘要： In the liquid crystal display device of this invention, each pixel region has first, second, third and fourth liquid crystal domains that define first, second, third and fourth predetermined tilt directions, respectively, in response to a voltage applied. The first through fourth directions are defined such that an angle formed between any two of the four is approximately equal to an integral multiple of 90 degrees. The first through fourth liquid crystal domains are arranged in two columns and two rows to define a matrix pattern and to be adjacent to each other. A drain extension line defines at least a part of a central opaque portion that selectively shields a boundary area, where each of the first, second, third and fourth liquid crystal domains contacts with another one of them, from incoming light. At least one islanded opaque portion, made of the same layer as a gate bus line, has a portion that overlaps with the drain extension line with a gate insulating film interposed between them. Thus, a VA mode liquid crystal display device with excellent display quality can be provided.

摘要： In a transistor adapted to suppress characteristic degradation resulting from fluorine contained in a deposited film, the concentration of fluorine contained in a gate insulating film (3) is reduced to 1.0×1020 atoms/cm3 or less. As a result, the transistor can provide excellent reliability even when it is continuously driven for a long period of time at a relatively high temperature.

摘要： A liquid crystal display of the present invention contains a first panel and a second panel being stacked. Adjacent pairs of polarizers (A to C) disposed on the panels form crossed Nicols. When the first panel produces a display according to a first display signal, the second panel produces a display according to a second display signal obtained from the first display signal. Each of the two joined panels is provided with a light diffusion layer having a light diffusing property. The provision of the light diffusion layers enables reducing moire pattern occurrences which would otherwise markedly increase when two liquid crystal panels are stacked. As a result, the liquid crystal display has high display quality.

摘要： The method of driving a liquid crystal display in accordance with one embodiment of the present invention is a method of driving a liquid crystal display whereby a first liquid crystal panels produces a display from a first display signal and the second liquid crystal panel produces a display a second display signal derived from the first display signal, the first and second liquid crystal panels being stacked on top of each other. The luminance of the first liquid crystal panel is extended based on the luminance extension ratio obtained from the gray levels for dots contained in the first display signal and a logical maximum gray level of input image data. The luminance of the second liquid crystal panel which produces a display from the second display signal is lowered by the amount by which luminance is extended on the first liquid crystal panel. A liquid crystal display with high display quality is realized by restraining decrease in saturation which would otherwise become obtrusive when two liquid crystal panels are stacked.
