Poval film

World Market Share: Number 1 Share 80% *Kuraray estimate

Optical Poval film is used as an important material in polarized film, indispensible for liquid crystal displays (LCDs). Possessing excellent transparency derived from Poval, polarized film absorbs light in a molecular axial direction and conducts it only in a single direction in a shutter-like function.

The Kuraray Group's strength is its integrated system of production using the raw material Poval. Presently, production facilities are being expanded at the Kurashiki Plant to meet worldwide demand.

Light can pass through polarized film in only a unidirectional pattern.
When voltage is applied to liquid crystals, light travels in one direction;
however, when the voltage is stopped, light waves are scattered.
