Abstract: The present invention provides a liquid crystal display. By locating a color light emitting layer which is mainly manufactured with quantum dot material in the liquid crystal display panel, the color gamut performance of the liquid crystal display is promoted. Meanwhile, by locating the unidirectional light guide thin film at the illuminating side of the liquid crystal display panel, the lights emitted from the color light emitting layer can propagate outward through the unidirectional light guide thin film, and exterior light is blocked and reflected by the unidirectional light guide thin film and cannot propagate to the color light emitting layer to excite the quantum dots to emit light. Thus, the issue that the contrast drops or even color shift happens because the traditional quantum dot display can be easily excited by the exterior light can be prevented to promote the display quality of the liquid crystal display.

Abstract: The present invention provides a quantum dot liquid crystal display device. The quantum dot liquid crystal display device has a color filter substrate (10) that includes a first base plate (11), a quantum dot color filter (12) arranged on one side of the first base plate (11) that is adjacent to a liquid crystal layer (30), a one-way light guide film (13) arranged on one side of the first base plate (11) that is distant from the liquid crystal layer (30), and an anti-reflection transmission-enhancing film (14) arranged on the one-way light guide film (13). The one-way light guide film (13) prevents light from getting incident into the interior of the liquid crystal display device to excite quantum dots so as to overcome the issues of contrast lowering and color shifting caused by external natural light exciting the quantum dots. The anti-reflection transmission-enhancing film (14) helps overcome the issues of glare and reflection light image of the liquid crystal display panel, thereby improving comfortableness of viewing of the viewers. Thus, the quantum dot liquid crystal display device has high contrast and low surface reflectance and does not induce image doubling and eye harshness caused by glare so as to provide enhanced comfortableness of viewing.

Abstract: The present invention provides a method for patterning a quantum dot layer and a method for manufacturing a quantum dot color filter. The method for patterning a quantum dot layer according to the present invention uses a photoresist layer having a patterned structure as a shielding layer to subject a monocolor quantum dot layer to etching to form a patterned quantum dot layer. The method simplifies the constituent components for making a quantum dot paste that is used to form a quantum dot layer and simplifying a surface chemical environment of the quantum dots to thereby increasing light emission efficiency of the quantum dot. Further, the method may manufacture a fine quantum dot pattern, greatly improving the resolution of the patterned quantum dot layer. The method for manufacturing a quantum dot color filter according to the present invention is applied to manufacturing a quantum dot color filter on the basis of the above-described method for patterning a quantum dot layer and the quantum dot color filter so manufactured has a fine quantum dot pattern, the light emission efficiency of the quantum dots being high to thereby effectively improve the resolution and backlighting utilization of a display device.
