ABSTRACT:
This invention relates to a liquid crystal display panel comprising a structural element having therein at least two functions such as, e.g., a transparent conducting film, a protective film for a polarizing film, a phase retardation film, a color filter, a light guide sheet, a light diffusion sheet, and a light condensing sheet, wherein the at least two functions of said structural element are performed by a sheet or film and said film is constituted of a thermoplastic resin having norbornane repeat units. This liquid crystal display panel permits practical use of films with a plurality of liquid crystal display panel functions that have not been used in practice by the conventional plastic films, by using films having high optical properties, heat resistance, moisture resistance, dimensional stability, moldability, and mechanical strength, resulting in the ability to reduce the number of films needed, the formation of a thinner and reduced weight panels, and in addition providing excellent display image sharpness.
