Quantum dot liquid crystal display device

A quantum dot liquid crystal display device, comprising a liquid crystal display panel and a backlight module arranged under the liquid crystal display panel;

• wherein the liquid crystal display panel comprises a color filter substrate and an array substrate that are opposite to each other and a liquid crystal layer arranged between the color filter substrate and the array substrate;
• wherein the color filter substrate comprises a first base plate, a quantum dot color filter arranged on one side of the first base plate that is adjacent to the liquid crystal layer, a one-way light guide film arranged on one side of the first base plate that is distant from the liquid crystal layer, and an anti-reflection transmission-enhancing film arranged on the one-way light guide film;
• wherein the one-way light guide film has a light guiding direction that is consistent with a lighting direction of the backlight module;
• wherein within a wavelength range of visible light, the anti-reflection transmission-enhancing film has a maximum reflectance that is less than 3%;
• wherein the anti-reflection transmission-enhancing film has a single-layer structure, a double-layer structure, or a multiple-layer structure having three or more layers;
• wherein the quantum dot color filter comprises therein a quantum dot material that comprises one of II-VI group quantum dot materials, III-V group quantum dot materials, I-III-VI group quantum dot materials, or multiple ones thereof;
• and
• wherein the quantum dot material of the quantum dot color filter comprises one of CdSe, CdS, CdTe, ZnS, ZnSe, CuInS, and ZnCuInS or multiple ones thereof.
