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： The liquid crystal display comprises a first substrate 2 including a first pixel electrode 12a and a second pixel electrode 12b, a second substrate 4 with an opposed electrode 22 formed on, and a liquid crystal layer 6 sealed between the first substrate 2 and the second substrate 4. The thickness d1 of the liquid crystal layer 6 on the first pixel electrode 12a in the first pixel region 8R, 8G is larger than the thickness d2 of the liquid crystal layer 6 on the second pixel electrode 12b in the second pixel region 8B. The first pixel region 8R, 8G includes a first partial region 11a, and a second partial region 13a where the threshold voltage is higher than in the first partial region 11a. The second pixel region 8B includes a third partial region 11b, and a fourth partial region 13b where the threshold voltage is higher than in the third partial region 11b. The threshold voltage in the first partial region 11a and the threshold voltage in the third partial region 11b are equal to each other, and the threshold voltage in the second partial region 13a and the threshold voltage in the fourth partial region 13b are equal to each other. Thus, it is possible to prevent large changes in the chromaticity due to gradation and visual angle changes, which lead to the prevention of the occurrence of the coloring. Thus, it is possible to provide a liquid crystal display having good display quality.

摘要： A sub picture element electrode directly connected to a thin film transistor is disposed between a floating sub picture element electrode capacitively coupled to a control electrode and a gate bus line in order to prevent injection of electric charges from the gate bus line to the floating sub picture element electrode. Moreover, a shield pattern electrically connected to an auxiliary capacitance bus line is formed between the floating sub picture element electrode and a data bus line. This shield pattern avoids injection of electric charges from the data bus line to the floating sub picture element electrode.

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。
