The surface of an electrode in contact with the layer of a liquid crystal in a liquid crystal display device is coated with fluoroplastic or fluorocarbon polymer to maintain the liquid crystals oriented for a substantial time after rubbing the surface of the layer of fluoroplastic with a sheet of cloth or paper along a predetermined direction. The thus oriented molecules of the liquid crystal causes polarized light to be rotated, thereby allowing color modification and the on-off control of the display device in combination with polarizers in response to the application of an electric field to portions of an electrode sandwich in a liquid crystal display device.
