4.1: Distinguished Paper: Cavity Shape Control of the Roll‐to‐Roll Fabricated Novel Microstructure Film for Improving the Viewing‐Angle Characteristics of LCDs

A microstructure film with many micro cavities positioned behind small black dots has been developed for improving LCD viewing-angle characteristics. The micro cavities are fabricated by the self-alignment photolithography of the transparent photoresist using the black dots as photo masks. The cavity shapes are optimized by controlling the photolithography conditions.
