Abstract
A multicolor liquid crystal display panel including a first and a second transparent substrate sheet of glass, a color filter layer which forms a multiplicity of picture elements and which is interposed between the first and second sheets of glass, an electrode layer having picture-element electrodes corresponding to the picture elements, and a liquid crystal layer whose transmittance of light is locally varied by application of an electric field thereto through the picture-element electrodes. At least one of the first and second sheets of glass is formed of transparent glass ceramics or crystallized glass having a major crystalline phase which consists of crystals of a Li.sub.2 O-Al.sub.2 O.sub.3 -SiO.sub.2 system.
