ABSTRACT:
A chiral nematic type liquid crystal display device in which the twist angle of a torsional structure of a liquid crystal layer is as large as 180.degree. to 360.degree. and the birefringence of liquid crystal molecules is utilized. This liquid crystal display device is characterized in that: a liquid crystal layer is disposed between opposed substrates and orientation films formed of straight chain polymer having fluoro-alkyl side chain C.sub.n H.sub.m F.sub.2n+1-m (n being a natural number and m being a natural number of 0 or 2n or less) are provided on the respective inner surfaces of said substrates facing the liquid crystal layer.
