ABSTRACT:
An optical modulation device comprises a liquid crystal having bistability between a pair of parallel base plates oppositely spaced from each other. A plurality of structural members having side walls are arranged at a substantially equal interval between the pair of parallel base plates so as to be in contact with at least one of them. Further, side walls of the plurality of structural members are treated for horizontal orientation in parallel with the extending direction of the structural members, and have a wall effect for orienting liquid crystal molecules in the direction of the horizontal orientation treatment.
