Abstract
A chiral nematic liquid crystal composition, characterized in that a self-organizing type gelling agent is contained and the phase transition temperature between liquid crystal and isotropic phases is higher than the sol-gel transition temperature, a liquid crystal display device wherein the chiral nematic liquid crystal composition is put and held between a pair of substrates having an electrode, and a method for producing a liquid crystal display device wherein the chiral nematic liquid crystal composition is heated to a temperature of not lower than the phase transition temperature between liquid crystal and isotropic phases and then cooled down to room temperature.
