Liquid crystal display device provided with a liquid crystalline compensating film having a positive uniaxiality in a nematic hybrid orientation |
摘要 |
A liquid crystal display device having improved and broadened viewing angle characteristics. The device includes a liquid crystal cell of the twisted nematic type for driving sandwiched by a pair of upper and lower polarizing plates in which at least one compensating film is inserted between the liquid crystal cell and the upper polarizing plate or between the liquid crystal cell and the lower polarizing plate. Alternatively, two compensating films are respectively inserted between the liquid crystal cell and the upper polarizing plate and between the liquid crystal cell and the lower polarizing plate. The compensating film consists essentially of a liquid crystalline polymer showing optically a positive uniaxiality, the liquid crystalline polymer being fixed in a nematic hybrid orientational order. The device is further characterized by an angle between a tilt direction of the compensating film and a pretilt direction on a liquid crystal cell substrate opposed to a substrate for the liquid crystal cell for driving closest to the compensating film in the range of 165 DEG and 195 DEG C.
