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

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.
