Claim 19:
20. A method of manufacturing a display panel, comprising:
forming a first substrate, comprising forming a plurality of light sources on a first base substrate;
forming a second substrate, comprising:
forming a light conversion structure on a second base substrate, wherein the light conversion structure comprises at least a plurality of quantum dot structures;
forming a plurality of extinction structures on a side of the light conversion structure away from the second substrate by a patterning process, wherein a first channel is formed between any two adjacent extinction structures; and
forming a plurality of first optical structures on a side of the light conversion structure away from the second base substrate and in the plurality of first channels by a printing process;

aligning the first substrate and the second substrate; and
forming a filler portion between the first substrate and the second substrate,
wherein 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 a light-absorbing material; and
wherein orthographic projections of the plurality of light sources on the first base substrate at least partially overlap orthographic projections of the plurality of first optical structures on the first base substrate, an orthographic projection of the light conversion structure on the first base substrate at least partially overlaps the orthographic projections of the plurality of first optical structures on the first base substrate, and the orthographic projections of the plurality of first optical structures on the first base substrate fall within an orthographic projection of the filler portion on the first base substrate.
