Abstract
A display panel and a manufacturing method thereof, and an electronic terminal are provided and including a driving circuit layer, a planarization layer, an electrode layer, and a light-emitting layer which are stacked from bottom to top. The driving circuit layer includes driving circuits. The planarization layer includes first planarization portions and second planarization portions which are arranged in a same layer. The electrode layer includes electrode groups. The light-emitting layer includes light-emitting devices. The first planarization portion is disposed on a side of the driving circuit close to the electrode layer, and the second planarization portion is disposed on a side of one of the electrode group close to the driving circuit layer. A thickness of the second planarization portion is greater than a thickness of the first planarization portion.
