Liquid crystalline polymer film for liquid crystal displays

Abstract

To improve quality of images of liquid crystal displays (LCDs) such as their viewing angle performance and coloration, we have developed liquid crystalline retardation film technology by using rod-like liquid crystalline polymer. Comparing with the conventional stretched retardation film, the liquid crystalline film has advantages in its unique orientation form and small thickness. Well-controlled structures such as twisted nematic, hybrid nematic and homeotropic structure enable ideal compensation of STN, TN, ECB, VA and IPS LCDs.
