摘要： The liquid crystal light modulator includes a first substrate (10) and a second substrate (20) disposed between two polarizers, and a pair of electrode structures (24, 24). The substrates include homeotropic alignment films (12) and (22), and at least one of the substrates has a function of aligning C-directors of liquid crystal molecules along one direction. The one direction forms an azimuth angle in the range of 35 to 55 degrees with the direction of the electric field generated by the pair of electrode structures (24, 24). A liquid crystal composition layer (31) contains a ferroelectric liquid crystal composition having a chiral smectic C phase or a liquid crystal composition that has an achiral smectic C phase and negative dielectric anisotropy. Light transmittance is modulated by the electric field generated by the electrode structures (24, 24) changing the birefringence index of the liquid crystal composition layer (31).
