A display panel and a manufacturing method thereof, and a display device. The display panel includes: a base substrate including a display area including a first and a second display area; a first group of light-emitting devices located at the first display area; a first group of pixel driving circuits located at the second display area, configured to drive at least one first light-emitting device; a second group of light-emitting devices located at the second display area; and a second group of pixel driving circuits located at the second display area, and including a plurality of second pixel driving circuits configured to drive the plurality of second light-emitting devices. In a direction perpendicular to the base substrate, one group of pixel driving circuits of the first and second group of pixel driving circuits is located between the other group of pixel driving circuits and the base substrate.
