摘要： PROBLEM TO BE SOLVED: To carry out optical modulation without need of a gap forming process for filling a liquid crystal, enabling the structure having a uniform and large area without formation of orientation defects, and attaining improved strength against the outer stress, a high speed and high contrast. SOLUTION: The modulator has a liquid crystal-resin composite 3 composed of a ferroelectric liquid crystal 1 having a spontaneously polarizable characteristics and exhibiting a chiral smectic C phase and a three-dimensional reticular synthetic resin 2, two transparent substrates 5a, 5b on each of which a transparent electrode 4a or 4b is formed and which hold the liquid crystal-resin composite 3 between them in such a manner that the transparent electrodes 4a, 4b are each interposed inside each of the transparent substrates 5a, 5b and allowed to stick to the liquid crystal-resin composite 3, and a power source 8 for applying the direct current voltage having both polarities to the two transparent electrodes 4a, 4b. It becomes unnecessary to control the gap using a seal resin and becomes possible to produce the optical modulator having a uniform and large area by forming the firm liquid crystal-resin composite 3 by dispersing the synthetic resin 2 into the low molecular weight ferroelectric liquid crystal 1 in a high concentration and coating the mixture thus obtained on the transparent electrodes 4a, 4b with the liquid, each being formed on the transparent substrates 5a, 5b.

摘要： PROBLEM TO BE SOLVED: To control the alignment of a liquid crystal without using a high temperature calcining process so that a plastic substrate can be used as a transparent substrate and to attain a light and large-sized device. SOLUTION: A fluorocarbon resin is applied to transparent electrodes 3a, 3b formed on transparent substrates 4a, 4b to form fluorocarbon resin alignment films 1a, 1b which control the alignment of the liquid crystal. A voltage outputted from a voltage supply 7 is applied to the transparent electrodes 3a, 3b to control the molecular arrangement of the liquid crystal 2.
