Abstract
A display panel includes a first base substrate, a plurality of light sources on the first base substrate, a second base substrate opposite to the first base substrate, a light conversion structure on the second base substrate, a plurality of extinction structures on a side of the light conversion structure facing the first base substrate, a first channel formed between any two adjacent extinction structures, a plurality of first optical structures on a side of the light conversion structure facing the first base substrate, wherein the plurality of first optical structures are respectively located in the first channels each between any two adjacent extinction structures, and a filler portion between the plurality of light sources and the plurality of first optical structures. The filler portion contains a material with a refractive index greater than that of a material of the first optical structure, and the extinction structure contains light-absorbing material.
