Disclosed are a color filter substrate and a manufacturing method therefor, a display panel, and a display device. The color filter substrate comprises multiple red sub-pixel regions, multiple green sub-pixel regions and multiple blue sub-pixel regions, wherein a target quantum dot material is provided in each of the blue sub-pixel regions, and the target quantum dot material is used for converting part of the initial blue light, emitted by a backlight source and entering the blue sub-pixel region, into light of a target color; the peak wavelength of the light of the target color is greater than the peak wavelength of the initial blue light; a red quantum dot material is provided in each of the red sub-pixel regions, and the red quantum dot material is used for converting the initial blue light, emitted by the backlight source and entering the red sub-pixel region, into red light; a green quantum dot material is provided in each of the green sub-pixel regions, and the green quantum dot material is used for co
