    摘要: A phase plate comprises, as a birefringent layer, a film obtained by stretching and orienting a sheet of a thermoplastic saturated norbornene resin, which has been formed by melt forming. The phase plate of the invention is such that the birefringent layer is optically even at the whole surface, and such optical evenness remains constant even by changes of temperature, humidity and/or the like. The phase plate of the invention can be used in parts for polarization microscopes, parts for liquid crystal displays, etc., and is particularly suitable for use in a phase plate for liquid crystal displays.
