Abstract
The present application provides an array substrate, a manufacturing method thereof, and a display panel thereof. A first ink is coated on an active region of an underlay substrate to form an active layer pattern, a second ink is coated on a channel region on the underlay substrate to form a protective layer pattern. Then the active layer pattern and the protective layer pattern is cured to form films, and to simultaneously form an active layer and a protective layer. The protective layer can protect the channel region of the active layer to mitigate an issue of the conventional corroded and contaminated metal oxide.
