Display panel and display apparatus

A display panel, wherein the display panel comprises:

• a substrate, comprising a plurality of sub-pixel regions;
• a plurality of light emitting devices, arranged on one side of the substrate and corresponding to the plurality of sub-pixel regions one by one;
• a first pixel definition layer, arranged on one side, facing away from the substrate, of the plurality of light emitting devices;
• wherein the first pixel definition layer comprises first opening regions corresponding to the plurality of sub-pixel regions one by one;
• a plurality of quantum dot layers, arranged on the side, facing away from the substrate, of the plurality of light emitting devices;
• wherein the plurality of quantum dot layers are arranged in at least part of the first opening regions;
• and
• a plurality of first refractive index patterns, arranged between the plurality of light emitting devices and the plurality of quantum dot layers, wherein a refractive index of each of the plurality of quantum dot layers is greater than that of each of the plurality of first refractive index patterns;
• wherein the plurality of light emitting devices are blue light emitting devices;
• the plurality of sub-pixel regions comprise:
• a plurality of red sub-pixel regions, a plurality of blue sub-pixel regions, and a plurality of green sub-pixel regions;
• the first refractive index patterns and the quantum dot layers are only arranged in first opening regions corresponding to the plurality of red sub-pixel regions and the plurality of green sub-pixel regions;
• and
• when the display panel further comprises a prism structure, an orthogonal projection of the prism structure on the substrate and the plurality of blue sub-pixel regions do not overlap each other.
