Abstract
An array substrate, display panel, display apparatus, and method for manufacturing the array substrate are provided. Array substrate includes pixel driving circuit and peripheral driving circuit. Array substrate further includes a plurality of thin film transistors including first type of thin film transistor electrically connected into peripheral driving circuit for outputting driving signal and second type of thin film transistor connected to peripheral driving circuit for outputting scanning signal. The thin film transistor includes an active layer of oxide semiconductor including at least one sub-layer. Compared with second type of thin film transistor, active layer of first type of thin film transistor has more sub-layers, and thickness of active layer of first type of thin film transistor is larger. Each sub-layer of the active layer of the second type of thin film transistor is in a same layer as the active layer of the first type of thin film transistor.
