Abstract
Provided are a display panel and a manufacturing method thereof, and a display device. The display panel includes: a base substrate including a display area and a peripheral area; a plurality of sub-pixels, each sub-pixel including a light-emitting element and a pixel driving circuit; a plurality of gate lines and light-emitting control lines; a gate driving circuit located at the display area and including cascaded multistage gate driving units, one or more stages include gate driving sub-circuits including a first and a second gate driving sub-circuit spaced apart by pixel driving circuits of a first group of sub-pixels; and a light-emitting control driving circuit located at the display area and including cascaded multistage light-emitting control driving units, one or more stages include light-emitting control driving sub-circuits including a first and a second light-emitting control driving sub-circuit spaced apart by pixel driving circuits of a second group of sub-pixels.
