ABSTRACT:
A color filter using liquid crystal compounds is disclosed. Mixtures of nematic and cholesteric liquid crystal compounds are sealed between a pair of transparent plates to construct a liquid crystal cell, and a pair of polarizer plates is disposed at both sides of the cell.
The color of the light passing through the filter device can be controlled and changed by changing the angle of the polarized plane defined by each polarizer plate and by changing the ambient temperature surrounding the device or the liquid crystal mixtures within the cell.
