The WV film successfully enlarged the field of view of the TN mode and made TN popular for larger size applications such as PC monitors. The hybrid alignment of the PDM (polymerized discotic material) layer is also suited for the OCB mode, which is promising as a nextgeneration LCD-TV because of fast panel response and a wide viewing angle. This paper describes recent technological progress in WV films, especially for OCB.

We have successfully commercialized a novel optical compensation film, OCB-WV film, for OCB-LCD-TVs which has fast response time and wide viewing angle. The OCB-WV film consists of a 45degree-aligned discotic layer and a high Rth biaxial TAC film, which is suited for a roll-to-roll polarizer manufacturing process. This OCB-WV has brought out the excellent features that OCB intrinsically has, making nextgeneration fast-response LCD-TVs possible and free from image blurring in conjunction with an impulsive driving scheme.

High quality cathode with high deposition rate of thin films and long target life time is required for manufacturing TFT-LCD and semiconductor. We developed WV(wide view) sputtering cathode with wide erosion area and high deposition rate. Ti thin film thickness variation in WV cathode is below 5% for 380 kWh target life time. Al thin film thickness using normal cathode is decreased about 20%. By using WV cathode, target using efficiency was improved 40%. in comparison with normal cathode.

Because of its weak points that narrow viewing angle and grayscale inversion, 'bare' twisted nematic (TN) LCD has some limits to use as a display device, though its great strong points that low cost, high yield, simple design, high transmittance and normally white. The 'WideView(WV)' film which introduced by Fuji co., has been good solution to extend the viewing angles of TN mode, therefore that film have been used generally for TN panels needed wide viewing angle. This paper introduce the research to find the parameters of the Wide view film and a TN panel which affect viewing angle characteristics and how to adjust those parameters.
