We have developed an over 60-inch size Moth-eye anti-reflection surface, which has original shaped nanostructures. The minimum reflectance was 0.02% and the average was less than 0.04% with little wavelength dependence. Moreover an anti-glare function was added. The 60-inch LCD applied AG Moth-eye surface had an excellent visibility in bright environments.

29.3: Novel Wide-View Circular Polarizers Using Negative and Positive AC Plates

Akira Sakai; Kazuyoshi Sakuragi; Masahiro Hasegawa; Kazuhiko Tsuda; Nobuaki Yamada; Kenji Okamoto

Novel wide-view circular polarizers for VA-LCDs have been developed. In our new designs, no sophisticated retarders such as biaxial AB plates (nx>nz>ny) are required. Alternatively, negative and positive AC plates (nx ny>nz respectively) are employed to suppress the off-axis light leakages. Three promising configurations will be discussed.
