ABSTRACT:
A liquid crystal display device comprising: a first substrate having a signal electrode and a scanning electrode insulated from each other through an insulating layer, said first substrate being further provided with a switching transistor and a pixel electrode both in association with an intersection of said signal electrode and said scanning electrode; a liquid crystal layer containing a liquid crystal material of a positive dielectric anisotropy dispersed or impregnated in a transparent fluoro-type polymer of a fluoroalkyl acrylate or metacrylate or its copolymer with an alkyl acrylate or metacrylate; and a second substrate having a counter electrode to be placed at least opposite to said pixel electrode, said first and second substrate being disposed as opposed to each other so as to sandwich said liquid crystal layer.
