Abstract
The present invention provides an array substrate and manufacturing method thereof. The array substrate includes a thin film transistor including a gate, an active layer, a gate insulation layer, a source, and a drain. The active layer includes a first active layer and a second active layer laminated with one another, and material of the first active layer and the second active layer are different, to increase the on-state current of the thin film transistor. The present invention increases the on-state current by reducing a contact barrier with the gate insulation layer or reducing a depletion area of the active layer.
