Patent ID: 7405787

Claim:
A method of using a liquid crystal display comprising: a front panel comprising a front alignment layer having an alignment direction; a rear panel comprising a rear alignment layer having an alignment direction; and a liquid crystal layer between the front and rear alignment layers; wherein at least one of the front and rear panels further comprises a polarizer, said polarizer comprising a thin crystal film manufactured from a plurality of aromatic organic compounds, and the interplanar distance of the thin crystal film in the direction of any optical axis is 3.4±0.3 Å wherein the liquid crystal layer has a rotational twist angle of about 90°, a pre-tilt angle of not more than 2°; and the method comprising the step of setting the direction of liquid crystal directors coinciding with an off-normal viewing direction of the liquid crystal display at the mid-point of the rotational twist when a voltage is applied to the liquid crystal layer by selecting the alignment, material and thickness of the liquid crystal layer whereby a maximum image contrast is achieved in the off-normal viewing direction, wherein the direction of the liquid crystal directors coincides with an off-normal viewing direction in the range of an azimuth angle of from 15 to 35 degrees in the voltage-on state and the contrast becomes the largest in such a direction.
