Abstract:
A display device having a pair of electrode layers inside a pair of opposed substrates, and a light-modulating layer comprising liquid crystal phases and polymer phases as holograms being between the electrode layers;wherein at least one of the two pairs of substrates and electrode layers is transparent, said electrode layers are patterned to form picture elements arranged in a matrix, said light-modulating layer comprises picture element groups of 2 n kinds distributed substantially uniformly in stripes or in mosaic where n is a natural number more than one, and when k is a natural number less than or equal to n, holograms are formed on each k-th picture element groups so as to diffract irradiated light and turn it in a direction of left eyes of observers while other holograms are formed on each (k+n)-th picture element groups so as to diffract irradiated light and turn it in a direction of right eyes of observers, whereby independent picture images are provided for plural observers at different positions.
