Liquid crystal display device having first and second substantially transparent insulative plates having front and rear surfaces with said plates being arranged so that the rear surface of the first plate and the front surface of the second plate face each other. An antireflection coating is disposed on at least one of said front and rear surfaces of said front plate. A conducting coating is carried on said rear surface of said first plate and said front surface of said second plate. Means secures the first plate to the second plate so that there is a space provided between said conductive layers. A layer of liquid crystal material is disposed in said space.
