A display panel, a manufacturing method therefor, and a display apparatus. The display panel (100) comprises a light-emitting device layer (110), an encapsulation layer (120) and an optical regulation layer (130), which are successively stacked, the optical regulation layer (130) comprising first lens structures (131) located on the side of the encapsulation layer away from the light-emitting device layer, and a planarization layer (132) located on the sides of the first lens structures away from the light-emitting device layer, and on the exposed side of the encapsulation layer away from the light-emitting device layer, the surfaces of the sides of at least part of the first lens structures (131) away from the light-emitting device layer (110) having relief appearances.
