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.
Claims8
A multicolor liquid crystal display panel comprising:
- a first and a second transparent subtrate sheet of glass, wherein at least one of said first and second sheets of glass is formed of a transparent glass ceramic having a major crystalline phase of crystals of a Li.sub.2 O--Al.sub.2 O.sub.3 --SiO.sub.2 system, said crystals comprising beta-eucryptite crystals having a crystal grain size which is not greater than 0.1 microns;
- a color filter layer forming a plurality of picture elements;
- an electrode layer having picture-element electrodes corresponding to the picture elements;
- and
- a liquid crystal layer, the transmittance of light through which is locally varied by application of an electric field thereto through the picture-element electrodes;
- wherein said color filter layer, said electrode layer and said liquid crystal layer are interposed between the first and second sheets of glass.
A method of manufacturing a multicolor liquid crystal display panel comprising:
- providing a first and a second transparent substrate sheet of glass, wherein at least one of said first and second sheets of glass is formed of a transparent glass ceramic having a major crystalline phase of crystals of a Li.sub.2 O--Al.sub.2 O.sub.3 --SiO.sub.2 system, said crystals comprising beta-eucryptite crystals having a crystal grain size which is not greater than 0.1 micron;
- providing a color filter layer which forms a plurality of picture elements;
- providing an electrode layer which has picture-element electrodes corresponding to the picture elements;
- providing a liquid crystal layer, the transmittance of light through which is locally varied by application of an electric field thereto through said picture-element electrodes;
- and
- interposing said color filter layer, said electrode layer and said liquid crystal layer between said first and second sheets of glass.
