Liquid crystal display device

摘要

Provided is a twisted nematic liquid crystal display device which is improved on viewing characteristics of a display contrast, gray-scale characteristics and a display color. The twisted nematic liquid crystal display device includes a liquid crystal display comprising a liquid crystal cell of a TN type for driving sandwiched by a pair of upper and lower polarizing plates in which, at least one compensating film, which is essentially constituted of a liquid crystalline polymer which optically shows a positive uniaxiality and which is fixed in a nematic hybrid orientational order, is inserted between the liquid crystal cell and the upper polarizing plate, or between the liquid crystal cell and the lower polarizing plate, or at least two compensating films, each of which is essentially constituted of a liquid crystalline polymer which optically shows a positive uniaxiality and which is fixed in a nematic hybrid orientational order, are respectively inserted between the liquid crystal cell and the upper polarizing plate, and between the liquid crystal cell and the lower polarizing plate; and an angle between a tilt direction of a 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 is in the range of 165 to 195 degrees.
