Abstract
A display panel and a method for fabricating the same are provided. The display panel includes: a base substrate; a first thin film transistor on one side of the base substrate, the first thin film transistor comprising: a first active layer, a first protection layer, a second protection layer, a first source and a first drain; wherein the first protection layer and the second protection layer are on one side of the first active layer away from the base substrate, and are separated from each other; the first protection layer and the second protection layer are configured to protect the first active layer from being etched during forming of a via-hole corresponding to the first source and/or a via-hole corresponding to the first drain.
