摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display which has a simpler configuration by optimizing a compensation film and/or further a liquid crystal layer, wherein light leakage in a black display is extremely little and tone reversal is not caused over a large visual angle range. SOLUTION: Light leakage is almost eliminated by giving refractive indices A, B (for ordinary light and extraordinary light, respectively), thickness D j , tilt angle β j , and an azimuth Φ j to a compensation film 5 (the i-th sheet of N sheets) so that the sum of retardations with the corresponding virtually divided elements of the liquid crystal layer 2 (a minute liquid crystal layer 7 having uniform alignment (the j-th layer of N divisions)) is substantially zero. Further, tone reversal is eliminated by setting the average tilt angle α av of the liquid crystal layer 2 to be in a range of θ 0 av 0 , wherein θ 0 is a refraction angle at the designed maximum incident angle Θ i .

解决方案：通过给出折射率A，B（分别用于普通光和非常光），厚度D j ，倾斜角β j 几乎消除了漏光和方位角Φ j 到补偿膜5（第N页的N张片），使得延迟与液晶层2的相应虚拟分割元素的和（微分液体具有均匀取向的晶体层7（N分割的第j层）基本上为零。此外，通过将液晶层2的平均倾斜角α av 设定在θ <α av 的范围内来消除色调反转， SB> <90-θ 0 ，其中θ 0 是设计的最大入射角θ的折射角。版权所有（C）2008，JPO＆INPIT
