Abstract
The disclosure discloses a double-side liquid crystal display device and a backlight module thereof, the two metal wire grating polarized films with perpendicular metal wire gratings can utilize reflective light of the liquid crystal panel on one side to provide incidence light to the liquid crystal panel on the other side, the incidence light and the reflective light of the two liquid crystal panels compensate mutually to improve light utilization efficiency significantly and brightness of the two liquid crystal panels, and brightness of the two is unified simultaneously; moreover, the built-in metal wire grating polarized film substitutes the polarized plate attached on outside of the substrate, which can reduce processes and costs without sacrificing characteristics of polarized light; white backlight is formed by the blue LED, the red and green quantum dots to increase color gamut and brightness of the double-side display device.
