ABSTRACT:
A cholesteric liquid crystal (CLC) color filter substrate for reflective liquid crystal display devices comprises an alignment layer on a black substrate, a cholesteric liquid crystal (CLC) color filter on the alignment layer, the cholesteric liquid crystal (CLC) color filter including sub-color-filters red (R), green (G), and blue (B), and black matrices on boundaries of each of the sub-color filters R, G, and B. In addition, a cholesteric liquid crystal (CLC) color filter substrate for a reflective liquid crystal display devices comprises an alignment layer on a black substrate, a cholesteric liquid crystal (CLC) color filter on the alignment layer, the cholesteric liquid crystal (CLC) color filter including sub-color-filters R, G, and B, and boundaries of the sub-color filter R, G and B that reflect incident light having a long wavelength.
