Abstract
An array base plate includes a substrate; and a driving transistor and a switching transistor that are located on the substrate; the driving transistor includes a semiconductor layer; the switching transistor includes an active layer and a protecting layer, and the active layer includes two opposite main surfaces and a side surface that is located between outer contours of the two main surfaces; the protecting layer is located on a main surface of the active layer that is away from the substrate and covers the main surface and the side surface; the protecting layer and the semiconductor layer are arranged in a same layer, and a material of the protecting layer and a material of the semiconductor layer are a same metal-oxide-semiconductor material; and a carrier mobility of the protecting layer is less than a carrier mobility of the active layer.
