Vertical Alignment mode TFT‐LCD is divided into MVA mode through formation of protrusion, PVA mode that uses color filter ITO patterning and etc. Among these, R&D of PVA (Plus Viewing Angle) mode accomplished the practical Wide Viewing Angle through the several technical phases. The multi‐domain structure by the effect of fringe‐field and the application of biaxial compensation film are the examples. PVA mode has a characteristic of high transmittance compared other Wide Viewing Angle mode. However the recent requirements of diversification of a use and the requirements of improvement of a screen quality make the transmittance diminished by modification the cell parameter and etc. In the experimentation hereunder the structure of Gradual Y‐slit has accomplished over 10% of transmittance than the existing chevron pattern by applying this to T‐pattern. And the produced 17″SXGA T‐pattern panel shows the characteristics of 300 nits of brightness, 65% of color gamut, 600:1 contrast ratio and 25ms response time.
