Abstract
To improve quality of images of LCDs such as their viewing angle performance and coloration, liquid crystalline retardation film technology has been developed by using rod-like liquid crystalline polymer. The resulting liquid crystalline retardation film has several advantages over conventional uni- or biaxial stretched retardation film. By using liquid crystalline polymer, the direction of the principal axis can be determined freely for roll-to-roll lamination. Optical well-controlled structures such as twisted nematic, hybrid nematic and homeotropic structures can be stabilized for ideal compensation of various LCD modes including STN, TN, ECB, VA and IPS LCDs.
