Abstract
The present invention provides a liquid crystal display device. By mixing the quantum dots of different light emitting wavelengths in the liquid crystals to replace the color resist layer on the CF substrate, the liquid crystal display panel still can emit lights of RGB three colors in condition of without the color resist layer. Meanwhile, by mixing the dichroic dye with polarization function in the liquid crystals, the arrangement of one polarizer can be eliminated. In comparison with the traditional liquid crystal display panel, the liquid crystal display panel of the present invention eliminates the components, such as the color resist layer and the upper polarizer. The structure is simple, and the manufacture cost is low. Meanwhile, the color display quality of the liquid crystal display panel is great, and the light transmission ratio is high, which effectively promote the light use efficiency and the display performance of the liquid crystal display device.
