Abstract
A cholesteric liquid crystal color filter plate which includes a substrate, a first light filter region on the substrate wherein the first light filter region is formed of a cholesteric liquid crystal mixture which is permeable to a red wavelength zone by reflecting blue and green wavelength zones, a second light filter region on the substrate wherein the second light filter region formed of a cholesteric liquid crystal mixture is permeable to the blue wavelength zone by reflecting the green and red wavelength zones, and a third light filter region on the substrate wherein the third light filter region formed of a cholesteric liquid crystal-dye mixture is permeable to the green wavelength zone. The cholesteric liquid crystal-dye mixture is manufactured by mixing a cholesteric liquid crystal reflecting one of the red wavelength zone or the blue wavelength zone, with a dye absorbing the remaining wavelength zone which is not selected by the cholesteric liquid crystal.
