Abstract
This disclosure provides an array substrate, a method for fabricating the same, a display panel, and a display device, where a first photo-resist layer is stripped in a changed order in that the first photo-resist layer on a source-drain is stripped through wet etching before a ohm contact layer film and an active layer film are etched in an electrically-conductive channel area (i.e., an electrically-conductive channel of a TFT is etched) to form an ohm contact layer and an active layer.
