A manufacturing method of a color liquid crystal display panel, comprising:

• (1) providing the first substrate, wherein the first substrate is a thin-film transistor array substrate;
• (2) dropping a mixture comprising a liquid crystal material, a chiral dopant, and at least one dichroic dye on the first substrate to form dye-doped liquid crystal layers, wherein each of the dichroic dyes absorbs a light of a predetermined wavelength range;
• (3) providing a second substrate, wherein the second substrate is a package substrate and the second substrate comprises a second transparent substrate, a black matrix formed on the second transparent substrate, and a color filter arranged on the second transparent substrate and corresponding to the black matrix;
• (4) coating a sealant on a surface of the second substrate to form a sealant frame;
• (5) coating an electrically conductive resin on the second substrate at a location around and outside the sealant frame;
• and
• (6) laminating the second substrate and the first substrate together in a vacuum environment and subjecting the sealant frame to curing so as to hermetically seal the dye-doped liquid crystal layers between the first substrate and the second substrate.
