A method of manufacturing a liquid crystal display includes: forming a liquid crystal panel including two substrates and a liquid crystal layer interposed between the two substrates and irradiating light to the liquid crystal layer in a state in which a voltage is applied to the liquid crystal panel. The liquid crystal layer includes liquid crystal molecules and a reactive monomer, and the voltage applied to the liquid crystal panel is an AC voltage. The liquid crystal molecules are isotropic in a state that the voltage is not applied thereto and are anisotropic in a state that the voltage is applied thereto.
