Patent ID: 7253858

Claim:
A liquid crystal display device, comprising: first and second substrates facing and spaced apart from each other; a retardation layer on an outer surface of the first substrate; a linear polarizing layer on the retardation layer; a cholesteric liquid crystal color filter (CCF) layer on an inner surface of the second substrate; a liquid crystal layer between the first substrate and the CCF layer; a first cholesteric liquid crystal (CLC) polarization layer on an outer surface of the second substrate and having a first helical pitch of a first circular polarization direction; a second cholesteric liquid crystal (CLC) polarization layer on the first CLC polarization layer, the second CLC polarization layer having a second helical pitch of a second circular polarization direction opposite to the first circular polarization direction, wherein the CCF layer has the same circular polarization direction as the first circular polarization direction; and a backlight unit outside the second CLC polarization layer.
