Abstract
A display panel, a manufacturing method thereof, and a display device are provided. The display panel includes a driving backplate, functional component groups, and micro-LED chips. The functional component groups are integrated in regions where the micro-LED chips are not disposed and are multiplexed as alignment marks. In a mass transfer process of the micro-LED chips, the alignment marks are prevented from additionally occupying pixel space by using part of functional components multiplexed as the alignment marks under a precondition of ensuring alignment accuracy.
