Abstract
A liquid crystal display device includes first and second substrates spaced apart from each other with a liquid crystal therebetween. The liquid crystal display device adopts a cholesteric liquid crystal color filter. Each portion of the cholesteric liquid crystal color filter is designed to have an adjusted order parameter according to a wavelength of a corresponding color ray. Therefore, with the variously adjusted order parameters of the cholesteric liquid crystal color filter, an increase of the color shift due to a longer wavelength is prevented.
