摘要： An active matrix liquid crystal display device includes: a liquid crystal layer; two substrates sandwiching the liquid crystal layer; and electrodes respectively provided in the two substrates, the electrodes applying voltage across the liquid crystal layer. A first electrode (15) in the substrate including a pixel selecting element (11) has a striped electrode pattern (15c) aligning liquid crystal molecules along a stripe line direction when voltage is applied across the liquid crystal layer. A contact (25h) of the first electrode (15) with the selecting element (11) is formed in a region opposed to, along a film thickness direction, a first region to which a signal liner (GLi) is allocated. This provides a liquid crystal display device in which a contact is made with the pixel electrode having the striped electrode pattern having the periodical arrangement, while alignment disorder of the liquid crystal molecules is not reflected on display.

摘要： This invention relates to an image processing method for improving the quality of an image to be displayed on a display device and to a liquid-crystal display device using the same, and aims at providing an image processing method for providing wide viewing angle and excellent tonal-intensity viewing angle characteristic and a liquid-crystal display device using the same. Combined together are a higher-luminance pixel to be driven higher in luminance than the luminance data of an image to be displayed and a lower-luminance pixel to be driven lower in luminance than the luminance data, to determine a luminance on the higher-luminance pixel and luminance on the lower-luminance pixel as well as an area ratio of the higher-luminance and lower-luminance pixels in a manner obtaining a luminance nearly equal to a desired luminance based on the luminance data.

摘要： In a retardation film (c plate) for canceling the optical effect of a liquid crystal layer, the optical effect of the liquid crystal layer which is represented by Δnd/λ increases as the wavelength λ of incident light decreases. Accordingly, in order to cancel this effect, a negative retardation needs to be reduced as the wavelength of incident light increases. In a retardation film (a plate) for rotating the direction of polarization of light, an in-plane retardation needs to be increased as the wavelength λ of incident light increases. It is preferable that both of these retardation films be placed. However, compared to known technologies, light leakage can be suppressed even using only any one of the retardation films.
摘要翻译：在用于消除液晶层的光学效果的延迟膜（c板）中，由Deltand /λ表示的液晶层的光学效应随入射光的波长λ降低而增加。因此，为了消除这种影响，需要随着入射光的波长的增加而减小负的延迟。在用于旋转光的偏振方向的延迟膜（板）中，需要随着入射光的波长λ增加而增加面内延迟。最好放置这两个相位差膜。然而，与已知技术相比，即使仅使用任何相位差膜也能够抑制漏光。

摘要： A liquid crystal panel includes a TFT substrate, an opposite substrate and a liquid crystal layer formed of a liquid crystal, which is filled in a space between the TFT and the opposite substrates, and has a negative dielectric anisotropy. A quarter wave plate and a polarizer are arranged on a front surface of the liquid crystal panel, and a quarter wave plate and a polarizer are arranged on a back surface thereof. An optical compensation layer is formed on a surface of the opposite substrate facing the liquid crystal layer. The optical compensation layer is divided into a plurality of regions for each picture element, and the respective regions are made of polymer films, each having a different compensation capability Rth in a thickness direction.

摘要： First and second polarization plates are disposed on both sides of a liquid crystal panel in which thicknesses of a liquid crystal layer are set up depending on colors of color filters. Then, a first retardation film is disposed between the liquid crystal panel and the first polarization film, and a second retardation film is disposed between the liquid crystal panel and the second polarization film. Assuming that a maximum value of a refractive index in an in-plane direction out of principal indices of refraction is Nx, that a refractive index in an orthogonal direction to the direction of the refractive index which has the value of Nx is Ny, and that a thickness is d, the first and second retardation films are set to satisfy a difference in values of (Nx−Ny)×d equal to or less than 10 nm.
