This paper reviews the technologies of the wide view (WV) film. The WV film is an optical compensation film, which remarkably enhances the field of view of twisted nematic (TN) thin-film transistor liquid crystal displays (TFT-LCDs). We have recently developed a new WV film for the OCB mode, which promises a fast optical response speed and wide viewing angle LCD-TV. The WV film is made of a hybrid alignment polymerized discotic material (PDM) layer coated on a (tri-acetyl cellulose (TAC) substrate. The PDM layer alignment technology and the TAC retardation control technology give us the flexibility to develop a compensation film for any LCD mode and allow a cost effective roll-to-roll polarizer lamination process.
