Abstract
The present invention provides a color liquid crystal display panel, which includes: a plurality of mutually parallel layers of liquid crystal cells (2) and bonding members (8) bonding the plurality of layers of liquid crystal cells (2). Each of the liquid crystal cells (2) includes a thin-film transistor substrate (20), a package substrate (30), and a dye-liquid crystal layer (40) sealed between the thin-film transistor substrate (20) and the package substrate (30). The dye-liquid crystal layer (40) includes a liquid crystal material and a dichroic dye. The dichroic dye of each of the liquid crystal cells (2) absorbs light of a predetermined range of wavelength. The plurality of layers of liquid crystal cells (2) respectively absorbs lights of different ranges of wavelength. The present invention includes a dichroic dye combined in a liquid crystal material in order to use the dichroic dye to absorb light of some colors thereby achieving color displaying without using a conventionally used polarizer and manufacture of a color filter substrate, so that the manufacture cost of and the requirement for backlighting brightness by the liquid crystal display panel can both be reduced.
