Abstract:
1. A liquid crystal display device comprising a plurality of display pixels, each of the pixels comprising: a first transparent substrate; a first transparent electrode disposed on the first transparent substrate; an insulating film covering the first transparent electrode and comprising a plurality of elongated concave portions and a plurality of elongated convex portions extending in the same direction as the elongated concave portions; a second transparent electrode disposed on each of the elongated convex portions of the insulating film; a second transparent substrate; and a liquid crystal layer disposed between the first transparent substrate and the second transparent substrate, wherein the entire top surface of each of the elongated convex portions is covered by the second transparent electrode between two corresponding elongated concave portions, and the insulating film is formed of a single layer so that a top surface of the single layer is in contact with the second transparent electrode and a bottom surface of the single layer is in contact with the first transparent electrode.
