Abstract
A liquid crystal display device includes a first substrate, a pixel electrode and a counter electrode, an insulation film, and a first orientation film formed over the pixel electrode and the counter electrode on the first substrate, the first orientation film being responsive to a radiated polarized light to obtain an initial orientation direction. A second substrate is opposed to the first substrate, a second orientation film is formed over the second substrate, and a liquid crystal is sealed between the first and second substrates. The first and second orientation films are made of polyimide, the liquid crystal has negative dielectric anisotropy, and the liquid crystal display device is normally in a black mode. An angle formed between the electric field and the initial orientation direction of the first orientation film is in a range of greater than 0° to 45°.
