摘要： A liquid crystal display of a vertical alignment (VA) mode using a circular polarization plate is provided which can reduce light leak as observed along an oblique direction and achieve a high contrast ratio. The VA mode uses a liquid crystal layer of vertical alignment in an initial alignment state. A film having generally isotropic optical characteristics in an omnidirection is used as a protective film, on a liquid crystal cell side, of first and second polarization plates disposed outside the liquid crystal cell, and first and fourth retardation films have an Nz coefficient smaller than 1.

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 conventional thin membrane of aerogel, although achieving a low refractive index, retains some difficulty when it is to be applied to display apparatuses or the like, because of its low strength. Membranes produced by other methods are difficult to simultaneously achieve low refractive index and sufficient strength. The present invention provides an anti-reflecting membrane which is formed at least on one side of a plate transmitting visible light, is composed of fine inorganic oxide particles and a binder, contains a number of pores inside, and has an arithmetic average surface roughness (Ra) below 6 nm. The present invention also provides preferred embodiments of the display apparatuses provided with the membrane.
