Abstract

Provided are a display panel and a manufacturing method therefor, and a display apparatus. The display panel includes a plurality of sub-pixels of at least two colors and further comprises: a base substrate; a first electrode on the base substrate; an electron transport layer at the side of the first electrode facing away from the base substrate; a quantum dot light-emitting layer at the side of the electron transport layer facing away from the base substrate; and a second electrode at the side of the quantum dot light-emitting layer facing away from the base substrate. Materials of the quantum dot light-emitting layer of the sub-pixels of different colors are different. The electron transport layer is of an alloy heterostructure at least composed of a metal oxide and a metal chalcogenide. Contents of the metal chalcogenide in the alloy heterostructure at positions of the sub-pixels of different colors are different.
