Patent ID: 7843531

Claim:
A liquid crystal display device comprising: a liquid crystal composition including a liquid crystal and a polymerizable compound that is polymerizable by either active energy rays or active energy rays combined with heat, disposed between a pair of substrates composed of a first substrate having scanning electrodes, signal electrodes, pixel electrodes, and thin film transistors, for applying voltage to a liquid crystal layer, and a second substrate having a counter electrode, said first and second substrates being devoid of protrusions for aligning liquid crystal molecules; wherein in a state that liquid crystal molecules are present in a gap between a pixel electrode and at least either one of the signal electrodes and the scanning electrodes and tilted in a direction from said at least either one of the signal electrodes and the scanning electrodes toward said pixel electrode, said polymerizable compound is polymerized by active energy ray irradiation, or by both active energy ray irradiation and heat, with or without applying voltage between the electrodes; and wherein the amount of the polymerizable compound remaining in the liquid crystal composition after the polymerization is not more than 0.05 parts by weight per 100 parts by weight of the liquid crystal.
