In-plane field type liquid crystal display device comprising liquid crystal molecules with more than two kinds of reorientation directions

A liquid crystal display device comprising:

• a first substrate;
• a pixel electrode and a counter electrode being formed over the first substrate;
• 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 so as to obtain an initial orientation direction thereof;
• a second substrate opposed to the first substrate;
• a second orientation film formed over the second substrate;
• and
• a liquid crystal sealed between the first substrate and the second substrate;
• wherein the liquid crystal is driven by an electric field generated by the pixel electrode and the counter electrode formed over the first substrate;
• wherein the first and second orientation films are made of polyimide;
• wherein the liquid crystal has a negative dielectric anisotropy;
• wherein the liquid crystal display device is normally in a black mode;
• and
• wherein an angle formed between the electric field and the initial orientation direction of the first orientation film in accordance with the radiated polarized light is in a range of greater than 0° to 45° and 145° to less than 180°.
