Abstract
We have developed a wide viewing VA-LCD system by the microstructure film with internal air-micro cavities. This microstructure film is attached on LC panel and change the direction of some incident lights from LC panel by reflection at the air cavities. The scattering profile of the film can be controlled with the shape of air cavities according to the characteristics of LC panel. This time, LC alignment directions and BL distribution are optimized as well as the scattering profile of the microstructure film. The color shift and the CR at oblique angles are improved than the conventional VA-LCD.
