Paper Abstract

Angle dependent light control film (LCF) is a new film which scatters only incident lights from particular angles and transmits incident lights from all other angles. This unique light control function of LCF is caused by the microstructure in itself. The optical performance and properties described in this paper support that the principle of an angle dependent light control function can be explained mainly by diffraction due to the microstructure like a stack of various transmission volume phase gratings.
