Image display device employing optical compensation film |
摘要 |
There is disclosed an optical compensation film which is used for a liquid crystal display device to improve visual angle and gray scale properties. At least one protrusion is formed on a second transparent film having a second refractive index and is partly engaged with a first transparent film having a first refractive index. In the engaged area between the first and second transparent films, the progression direction of light at an overlapped portion in which the first and second transparent films are in contact with each other, is different from that of the light at a non-overlapped portion in which there is a gap between the first and second transparent films. The optical compensation film prevents gray scale inversion phenomenon and improves visual angle of a display device.
