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.

摘要： A reflective liquid crystal display apparatus realizing a bright image display without using a backlight is provided. In this reflective liquid crystal display apparatus, a reflecting electrode having a scattering property and a directional property is manufactured using a small number of steps. A pattern of unevenness, such as a polygonal pattern, a cylindrical pattern, and the like, is formed on an insulating substrate utilizing a material layer formed for composing switching devices. By causing the unevenness of the pattern to influence the surface contour of the reflecting electrodes, it becomes possible to give both a scattering property and a directional property to the surface of the reflecting electrodes.

摘要： A reflective-type display device having a light modulating layer, including a host dispersed with light scatterers, which is held between two transparent electrodes; and a light absorbing layer disposed in back of the light modulating layer. The size of each light scatterer or the nearest distance between the adjacent light scatterers is nearly equivalent to the wavelength of incident light at least in two-dimensional directions. The refractive index ratio relative to incident light between the light scatterers and host is changed from 1 to 1.5 or more depending on the magnitude of a voltage applied across the electrodes.
