Abstract
A liquid crystal color display device which comprises a first electrode; a first substrate whose surface has a property of orientating the molecules of a nematic liquid crystal parallel with said surface; a second electrode; a second substrate whose surface has a property of orientating the molecules of the nematic liquid crystal perpendicular to said surface; a nematic liquid crystal interposed between the first and second substrates; at least one polarizer; and a means whereby the birefringence of the liquid crystal cell is changed to display various colors.
