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.

摘要： The present invention has an object to eliminate viewing angle dependency in the upward, downward, and right- and left-hand directions, and compensate for optical retardation according to the viewing angle. The liquid crystal display device is provided with at least one optical retardation compensator plate inserted between a liquid crystal display element and polarizer plates. The liquid crystal display element is composed of a pair of electrode substrates and a liquid crystal layer sealed therebetween. The polarizer plates flank the liquid crystal display element. The optical retardation compensator plate has a negative refractive index anisotropy and an inclining refractive index ellipsoid. The liquid crystal layer is divided unequally into divisions having mutually different orientation directions, and the pretilt angle formed by the orientation films and the major axes of liquid crystal molecules in the liquid crystal layer is set within such a range that tone reversion does not occur in the opposite viewing direction when halftone is being displayed by applying to the liquid crystal a voltage that is close to the threshold voltage for the liquid crystal.
