Abstract
An array substrate includes a substrate, a gate electrode, a gate insulating layer and an active layer formed in sequence in a stack. The active layer includes a source transfer portion and a drain transfer portion separated from the source transfer portion and a channel integrally connected to the source transfer portion and the drain transfer portion. Contact resistances between the source transfer portion, the drain transfer portion and the channel are reduced, and interface defects of the channel are reduced, so that through the source transfer portion and the drain transfer portion, an on-state current of a thin film transistor is increased and an off-state current is reduced so that is the on/off ratio is raised to improve the performance of the array substrate.
