Display panel, manufacturing method therefor, and display apparatus

A manufacturing method for a display panel, comprising:

• preparing a light emitting device layer and forming an encapsulation layer on a side of the light emitting device layer;
• preparing a first lens structure on the encapsulation layer and making at least a portion of a surface of the first lens structure away from the light emitting device layer have an undulating morphology;
• and
• forming a planarization layer on the first lens structure and on an exposed encapsulation layer;
• further comprising:
• preparing a second lens structure, wherein the second lens structure and the first lens structure are separated by a portion of the planarization layer, and wherein one level of total reflection critical surface is formed between the second lens structure and the planarization layer, and another level of total reflection critical surface is formed between the planarization layer and the first lens structure.

• preparing a first lens structure on the encapsulation layer and making at least a portion of a surface of the first lens structure away from the light emitting device layer have an undulating morphology;
• preparing a sacrificial structure on an exposed encapsulation layer;
• coating a second light transmitting material between adjacent sacrificial structures;
• removing the sacrificial structure to obtain a second lens structure;
• and
• forming a planarization layer on the first lens structure, the second lens structure, and the exposed encapsulation layer;
• wherein the second lens structure and the first lens structure are separated by a portion of the planarization layer, and wherein one level of total reflection critical surface is formed between the second lens structure and the planarization layer, and another level of total reflection critical surface is formed between the planarization layer and the first lens structure.
