PURPOSE: To provide the optical modulating element having excellent characteristics by enabling easy pattern coating and easily executing coating only in the plural block chambers segmented by partition walls consisting of an electrical insulating material and the process for production of such element.
CONSTITUTION: This optical modulating element is constituted by using a liquid crystal/high-polymer composite film formed by dispersing liquid crystal particles into a high-polymer matrix. The liquid crystal/high-polymer composite film which consists of liquid crystal particles, polyvinyl alcohol (PVA) having 300 to 1,200 degrees of polymn. and 50 to 85% degree of saponification and superfine particles of silica and has 5/95 to 50/50 mixing ratios (by weight) of the PVA/ liquid crystal is used for the above-mentioned composite film. This process for production produces the optical modulating element by using such composite film.
