发明名称 PRODUCTION OF PHASE DIFFERENCE PLATE
摘要 PURPOSE:To produce the phase difference plate which allows liquid crystal display of a wide visual field angle by preventing the coloration when the liquid crystal display is viewed from diagonal. CONSTITUTION:A thermoplastic resin film is stretched with a vertical uniaxial stretching machine and thereafter, the film is reduced in the direction orthogonal with the first stretching direction with a tenter stretching machine by which the phase difference plate having high uniaxiality is produced in the process for producing the phase difference plate by stretching the thermoplastic resin film.
