Abstract

The invention discloses a quantum-dot color filter, a manufacturing method thereof and a display device and relates to the technical field of display, aiming at solving the problem that an existing display device is low in light-emitting efficiency. The quantum-dot color filter comprises a substrate, black matrixes and a quantum dot layer, wherein the latticed black matrixes and the quantum dot layer are positioned on the substrate, the quantum dot layer is positioned in lattices enclosed by the black matrixes, and the black matrixes are capable of reflecting light emitted by quantum dots in the quantum dot layer after the quantum dots are excited. When the display device provided with the quantum-dot color filter operates, backlight emits into the quantum-dot color filter to excite the quantum dots in the quantum dot layer, the quantum dots emit light, part of the light emitted by the quantum dots is emitted towards the black matrixes, and the black matrixes reflect such light to change a light propagation direction to make the light emit from an emergent face of the display device, so that light-emitting efficiency of the display device is improved. The quantum-dot color filter is applied to the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot color filter, a manufacturing method thereof, and a display device. Background technique [0002] A display device is a device used to display text, numbers, symbols, pictures, or images formed by a combination of at least two of the text, numbers, symbols, and pictures. An existing display device includes a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), a color filter substrate (Color Filter Substrate, CF Substrate), and filled in the thin film transistor array substrate and the color filter substrate The liquid crystal molecules between the two substrates, when the above display device is in operation, drive voltages are applied to the thin film transistor array substrate and the color filter substrate respectively to control the rotation direction of the liquid crystal molecules between the two substrates, so th...
