Abstract
A liquid crystal display device comprises a reflector made of a high-reflectance material, a light scattering layer formed on the reflector, the light scattering layer containing light scattering particles introduced into a transparent resin, a first transparent electrode formed on the light scattering layer, a transparent substrate opposed to the light scattering layer with a prescribed gap interposed therebetween, a second transparent electrode formed on the transparent substrate and having a portion that is opposed to the first transparent electrode, and a layer of a guest-host type liquid crystal introduced into the gap between the light scattering layer and the transparent substrate and having a portion that is sandwiched between the first and the second transparent electrode.
