The invention relates to the technical field of displaying, in particular to a
quantum dot color filter, a manufacturing method thereof and a
display device. The
quantum dot color filter comprises a plurality of pixels, a substrate and a filter layer, wherein each pixel comprises a plurality of color sub-pixels in different colors; at least one color sub-pixel is formed by a
quantum dot material; the color of light generated by exciting the
quantum dot material is the same as that of a corresponding color sub-pixel; and the filter layer is used for absorbing light rays of the non-excited
quantum dot material. The color filter is formed since quantum dots can present physical features of
fluorescent light of different colors under the
irradiation of a backlight source, so that the
transmittance of the color filter is increased, the brightness and colors of pictures are improved and enriched greatly, the display quality of images is improved, the user experience is enhanced, and meanwhile, the production cost is reduced to the maximum extent.
