ABSTRACT:
In accordance with a method of manufacturing a liquid crystal display device including, in a picture element, a first sub-picture-element region where a threshold voltage of the transmittance-applied voltage characteristic is Vth1and a second sub-picture-element region where a threshold voltage of the transmittance-applied voltage characteristic is Vth2,liquid crystal, which polymerizable components are added to, is filled into the space between a first and a second substrates; thereafter, a voltage V1slightly higher than the threshold voltage Vth1is applied to a liquid crystal layer, and is held for a certain length of time; subsequently, a voltage V2slightly higher than the threshold voltage Vth2is applied to the liquid crystal layer, and is held for a certain length of time; additionally, a voltage V3higher than a white-displaying voltage which is applied while the liquid crystal display device is in actual use is applied to the liquid crystal layer, and is held for a certain length of time; then, the polymerizable components are polymerized by irradiation of ultraviolet light; and thus polymers are formed in the liquid crystal layer.
