ABSTRACT:
The present invention provides a light-modulation element comprising at least: liquid crystal droplets having a particle size between 0.6 .mu.m-2 .mu.m, which have light-modulating functions to scatter light rays or transmit light rays and polymer matrix having an interstructure thickness of 0.5 .mu.m or less between the liquid crystal droplets. The light-modulation element works to scatter light rays or transmit light rays by turning on a voltage or turning off a voltage. The light-modulation element is produced by a polymerization process and a mixing step to separate out liquid crystal phases in a polymer matrix.
