An MVA-LCD (multi-domain vertical alignment LCD) that provides super-high image quality has been developed by newly introduced rubbing-less technology.A newly introduced "protrusion" designed on the TFT substrates and on the color filter substrates automatically controls the directors of the LC molecules. By this technology we have successively developed four-domain 15" MVA-TFT units that provide extremely wide viewing angle of more than 160 degrees, a high contrast ratio of 300:1 or more and a fast response of less than 25ms.
We investigated how to achieve desired optical properties of quarter wave retardation films (QWFs) that increase the viewing angle of time-sequential stereoscopic 3D liquid crystal displays (LCDs), such as high luminance, low crosstalk, low color change, and low head-tilt-angle dependency. These display properties were strongly affected by the out-of plane retardation (Rth) of the QWF. We developed QWFs whose in-plane and out-of-plane retardation are independently controllable by adjustment of a polymerized discotic material layer and a triacetate cellulose film, and 3D-LCDs with high viewing angle properties were realized using these QWFs whose Rth was nearly zero.

We have developed a new reverse dispersion retardation film with a thickness of 4 for IPS panels, which achieves excellent viewing angle performance, notably for oblique contrast ratio and color. HDR‐IPS panels applied this reverse retardation film could achieve a significant improvement of the halo viewing from oblique angle.
A reflective‐color TFT‐LCD with high contrast ratio (80:1) and high reflective (36%) has been developed using a vertical alignmet (VA) mode. Use of both the VA mode and a newly developed photo‐maskless for fabricating a diffusing reflector has achieved a high‐performance, simple and low‐cost reflective display.
