Novel WV film for wide‐viewing‐angle TN‐mode LCDs

Abstract— A new optical compensation film refered to as WV-EA film for TN-mode TFT-LCDs has been developed, resulting in higher contrast ratio, wider-viewing-angle characteristics, and improved color shift than their predecessors, especially in the horizontal direction. These features of the new WV film were achieved as a result of haze reduction and optimizing the optical characteristics of the polymerized discotic material layer and TAC film. These features are suitable for large-sized and wide-aspect-ratio LCD monitors and TVs.
