Display panel, method for manufacturing same, and display device

A display device, comprising:

• a display panel;
• wherein
• the display panel comprises:
• a base substrate;
• a plurality of light-emitting units disposed on the base substrate;
• a first light-transmitting layer disposed on the base substrate provided with the plurality of light-emitting units, wherein the first light-transmitting layer comprises a plurality of holes, and an orthographic projection of a first light-emitting unit in the plurality of light-emitting units on the base substrate is overlapped with an orthographic projection of a first hole in the plurality of holes on the base substrate;
• and
• a light-transmitting pattern disposed on the base substrate provided with the first light-transmitting layer, wherein the light-transmitting pattern comprises a plurality of light-transmitting structures, a first light-transmitting structure in the plurality of light-transmitting structures covers the first hole and at least a portion of the first light-transmitting layer, and a refractive index of a material of the light-transmitting pattern is greater than a refractive index of a material of the first light-transmitting layer.
