Abstract:
1. An LCD device comprising: a first substrate; a second substrate disposed to face the first substrate; a liquid crystal layer inserted between the first and second substrates; a cholesteric color filter layer disposed on the first substrate; and an auxiliary color filter layer disposed on the cholesteric color filter layer that transmits a fixed wavelength band of light progressing in a front viewing direction of the cholesteric color filter layer and filters every wavelength band of light progressing in a side viewing direction of the cholesteric color filter layer except the fixed wavelength band of light, a first polarizing film disposed between the auxiliary color filter layer and the liquid crystal layer that changes a circular polarization state of light into a linear polarization state of light; wherein the first polarizing film includes, a QWP (quarter wave plate) layer contacted with an upper side of the auxiliary color filter layer; one of a wired grid polarizing layer, a different colorific (or double colorific) polarizing layer and a carbon nanotube polarizing layer contacted with an upper side of the QWP layer.
