Abstract:
A liquid crystal display device comprising:a liquid crystal cell of a TN type for drive; a pair of polarizing plates sandwiching the liquid crystal cell; at least one compensating film which has a quasi extinction axis angle of 5 to 90 degrees as an absolute value and an optical rotating angle of 0.5 to 10 degrees as an absolute value, wherein signs of the extinction axis angle and the optical rotating angle are contrary to each other, is inserted between the liquid crystal cell and an upper polarizing plate, or between the liquid crystal cell and the lower polarizing plate, or at least 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, wherein an arrangement condition is such that a quasi fast axis vector of a compensating film and an easy axis vector of an electrode substrate nearer the compensating film of the liquid crystal satisfy an angular relation therebetween in the range of -30 to +30 degrees or +150 to +210 degrees.
