| 摘要 |
The present invention provides a liquid crystal display device. An optical film having negative uniaxial double refractive index ellipsoids is arranged below a semi-transmitting liquid crystal display cell and, thereafter, a lambda/4 phase difference plate, a lambda/2 phase difference plate and a polarizer are arranged. The orientation axis direction of the optical film having negative uniaxial double refractive index ellipsoids is substantially equal to the direction which is rotated by 90° in the clockwise direction from a resultant vector of the orientation axis direction of the upper orientation film and the orientation axis direction of the lower orientation film of the liquid crystal display cell. Further, phase lagging axis of the upper and lower lambda/4 phase difference plate is set substantially equal to the orientation axis direction of the optical film having negative uniaxial double refractive index ellipsoids.
