Claim:
1. A method of producing a liquid crystal display device comprising the steps of: (1) forming a liquid crystal layer containing a liquid crystal composition having a nematic phase and containing a polymerizable monomer between a first substrate and a second substrate; (2) thermally annealing the liquid crystal layer at a temperature higher by 10° C. or more than the liquid crystalline phase-isotropic phase transition temperature of the liquid crystal layer; (3) forming horizontal alignment films to which the alignment treatment is performed by light irradiation on the first substrate and the second substrate by the time of the step (2); and (4) polymerizing the polymerizable monomer after the step (2), wherein the horizontal alignment films are photo-alignment films containing polyvinyl cinnamate, and the liquid crystal layer comprises liquid crystal molecules containing a multiple bond other than the conjugated bonds of a benzene ring in the molecule structure.
