Abstract:
A liquid crystal display device can obviate the generation of an extinction pattern. In the liquid crystal display device, molecules of liquid crystal are arranged in the vertical direction with respect to the substrate at the time of applying no voltage. A plurality of protruding portions are scattered on a surface of one substrate which is brought into contact with the liquid crystal material in respective pixel regions, and projecting portions or recessed portions are provided about these protruding portions. The projecting portions or the recessed portions are substantially aligned with the directions of the respective polarization axes of one polarizer which is provided to a surface of one substrate at a side opposite to a liquid crystal side and the other polarizer which is provided to a surface of the other substrate at a side opposite to a liquid crystal side.
