Claim:
1. A display panel defining a plurality of sub-pixels for emitting light with different colors and comprising: a lighting device comprising a plurality of lighting parts corresponding to the sub-pixels; a color conversion layer comprising a plurality of bases corresponding to the sub-pixels; and a reflective sheet configured to reflect light having a wavelength within a range from 480 nm to 500 nm, the reflective sheet configured to permit light having a wavelength out of the range from 480 nm to 500 nm to pass through, wherein the lighting device comprises, a first lighting part emitting a first light having a wavelength within a range from 480 nm to 500 nm, and a second lighting part emitting a second light having a wavelength within a range from 450 nm to 460 nm, wherein each of the first light and the second light is monochromatic light of a first color, the bases corresponding to the first lighting part are doped with a plurality of quantum dot particles, the first light is converted to a monochromatic third light of a second color by the plurality of quantum dot particles, the second light is emitted from the display panel by passing through the color conversion layer and the reflective sheet, and portions of the first light not converted by the quantum dot particles are reflected back into the color conversion layer by the reflective sheet.
