ABSTRACT:
A substrate coated with a film of liquid crystal material having a uniform thickness is produced efficiently by applying the liquid crystal material to the electrode side of a substrate using an impregnating matter impregnated with the liquid crystal material, and such a method ensures uniform thickness even for a film of liquid crystal material having a large area. A liquid crystal optical device having a uniform optical quality and a large area is produced efficiently by coating a flexible substrate with a film of liquid crystal material using the method described above, laminating the coated flexible substrate with another flexible substrate, with the film of the liquid crystal material disposed between the electrode sides of the flexible substrates, and orienting the liquid crystal material in thus obtained laminate by subjecting the laminate to bending treatment.
