Zusammenfassung:A display panel and a display device are provided. By manufacturing a first via hole and a second via hole first, and then manufacturing a third via hole and a fourth via hole, the first via hole and the second via hole have been covered by a corresponding first drain electrode and first source electrode before performing hydrofluoric acid cleaning processes, and a first drain region and a first source region of a first oxide transistor are not affected by the hydrofluoric acid cleaning process, thereby allowing an oxide channel of the first oxide transistor to also be prevented from being affected.
