摘要： A transreflective or “semi-transmissive” liquid crystal display (LCD) device of the vertical alignment (VA) type is disclosed. The VA-LCD device includes a pair of spaced-apart substrates with a layer of liquid crystal (LC) material sandwiched therebetween. The LCD device also includes a polarization plate provided on one of the substrates, another polarization plate on the other substrate, and a matrix of rows and columns of pixels formed between the substrates. Each pixel has a reflection part and a transmission part. The LC layer is variable in thickness so that its portion at the transmission part is thicker than a portion at the reflection part. At the reflection part, an internal retardation plate having an optical phase difference is disposed between the LC layer and its associated substrate. This plate forms an angle of about 45 degrees with the absorption axis of each polarization plate.

摘要： In a color display device, when using white (W) sub-pixels in addition to subpixels of red (R) and green (G) plus blue (B) without increasing a wiring line number, the per-color pixel number in a unit area decreases so that the image resolution is deteriorated. The area and number of subpixels are adjusted in accordance with the visual sensitivity or luminosity required. Practically, the area of red (R) and blue (B) subpixels which are relatively low in luminosity is set to be about two times greater than the area of green (G) and white (W) subpixels that are relatively high in luminosity while letting the number of green (G) and white (W) subpixels be twice the number of red (R) and blue (B) subpixels. A larger subpixel is configured from a plurality of unit subpixels. A smaller subpixel is formed of a one unit subpixel.
摘要翻译：在彩色显示装置中，在不增加布线数量的情况下，除了红色（R）和绿色（G）以及蓝色（B）的子像素之外，当使用白色（W）子像素时，单位的单色像素数面积减小，图像分辨率下降。子像素的面积和数量根据所需的视觉灵敏度或亮度进行调整。实际上，发光度相对较低的红色（R）和蓝色（B）子像素的面积被设定为大于发光度相对较高的绿色（G）和白色（W）子像素的面积的两倍，而使绿（G）和白（W）子像素的数量是红（R）和蓝（B）子像素的数量的两倍。较大的子像素由多个单位子像素构成。较小的子像素由一个单位子像素形成。

摘要： A liquid crystal display featuring excellent visibility with both good brightness and a high contrast ratio uses a projection optical system in which a polarizing plate, a first phase plate and a second phase plate in which the retardation of each of the phase plates and a gradient of wavelength dispersion of the retardation can be freely set, a liquid crystal layer, and a reflection plate are arranged in parallel and a transmitted light is reflected by the reflection plate. A gradient of one of the phase plates is set to an extremely steep gradient, a gradient of the other phase plate is set to an extremely flat gradient, and the wavelength dispersion of a retardation composite value obtained from the liquid crystal layer and the two phase plates is approximated to a retardation curve expressed by a relational expression of (0.25+0.5n)&lgr;, where (n) is an integer and &lgr; is a wavelength (nm) of the transmitted light.
