ABSTRACT:
A liquid crystal display device which includes two substrates opposed to each other; electrodes respectively provided on surfaces of the two substrates, the surfaces opposing to each other; heat-resistant polymer films each having a generally smooth surface and respectively provided on the electrodes; a liquid crystal layer interposed between the heat-resistant polymer films and including a plurality of microscopic regions; and two polarizing plates interposing the two substrates. Each of the plurality of the microscopic regions in the vicinity of the heat-resistant polymer films has liquid crystal molecules aligned uniformly, and the liquid crystal molecules in different microscopic regions are arranged in different directions with respect to one another.
