An optical modulation device comprises a pair of base plates and a ferroelectric liquid crystal sandwiched therebetween. A plurality of structural members each having side walls are arranged in the form of stripes on one of the pair of base plates. A monoaxial treatment is applied to at least one of the pair of base plates in a direction parallel with or perpendicular to the extension direction of the abovementioned plurality of structural members.

An optical modulating device comprising a pair of base plates comprising a first base plate and a second base plate disposed in parallel with each other, and a chiral smectic liquid crystal sandwiched between the pair of base plates; a plurality of spacer members being arranged in the form of stripes on the face of said first base plate contacting the liquid crystal, a monoaxial orientation treatment being applied to the face of the second base plate contacting the liquid crystal in a direction forming an angle q0°≤q%, said chiral smectic liquid crystal being disposed in a layer thin enough to unwind the spiral structure of the chiral smectic liquid crystal and forming monodomain formed through a cholesteric phase during a temperature decreasing stage.
