Reflective-type liquid crystal display device including a single polarizer plate

Abstract

A reflective-type liquid crystal display device in accordance with the present invention includes: a first substrate including a light-reflective electrode; a transparent second substrate including a transparent electrode; a nematic liquid crystal layer, sandwiched between the first and second substrates, having negative dielectric anisotropy, and twisting with application of a voltage; a plurality of optical retardation compensation plates disposed on a light-entering side of the second substrate; and a polarizer plate disposed on the light-entering side of the second substrate, wherein surfaces of the first and second substrates undergo substantially vertical alignment processing, and liquid crystal has a natural pitch p, a layer thickness d, and a refractive index differece .DELTA.n with respect to characteristic polarization thereof selected so as to satisfy 0<.vertline.d/p.vertline.<1 and 135 nm.ltoreq..DELTA.n.times.d.ltoreq.1200 nm. Moreover, liquid crystal molecules on a surface of at least one of the first and second substrates tilt 3.degree. to 30.degree. with respect to a normal direction of that substrate. With this arrangement, a color-display-capable reflective-type liquid crystal display device with high contrast and excellent viewing angle characteristics can be obtained. Especially, such a reflective-type liquid crystal display device could be suitably applied to a liquid crystal display device with an integral pressure sensitive input device, provided with a touch panel.
