Claim Text:
1. A color liquid crystal display panel, comprising: a first substrate, a second substrate laminated on the first substrate, and dye-doped liquid crystal layers hermetically sealed between the first substrate and the second substrate, the dye-doped liquid crystal layers each comprising a liquid crystal material, a chiral dopant, and three dichroic dyes, each of the dichroic dyes absorbing light of a predetermined wavelength range of one of red, green, and blue colors, the first substrate comprising a first transparent substrate, a plurality of gate lines formed on the first transparent substrate, and a plurality of data lines formed on the first transparent substrate, the second substrate comprising a second transparent substrate, a black matrix formed on the second transparent substrate, and a color filter that comprises red, green, and blue filters arranged on the second transparent substrate at a location corresponding to the black matrix, the black matrix and the gate lines and the data lines collectively dividing the color liquid crystal display panel into a plurality of pixels; wherein the three dichroic dyes that respectively absorb red, green, and blue light are used in combination with the red, green, and blue filters to achieve color displaying; and wherein the three dichroic dyes that absorb light of red, green, and blue colors respectively are collectively mixed in the liquid crystal material of each of the dye-doped liquid crystal layers such that each of the dye-doped liquid crystal layers comprises the three dichroic dyes.
