Abstract:
1. A method of manufacturing an array substrate, comprising: providing a base substrate including a active region, a pixel region and wiring region; forming an oxide semiconductor layer and a source metal layer on the base substrate, wherein the oxide semiconductor layer being disposed under the source metal layer; patterning the source metal layer to form a source remaining pattern in the active region and a data line in the wiring region; patterning the oxide semiconductor layer to form a first oxide semiconductor pattern in the active region and a second oxide semiconductor pattern in the wiring region; patterning the source remaining pattern in the active portion to form a source electrode and a drain electrode such that the source electrode and the drain electrode are spaced apart from each other, the source electrode and the drain electrode substantially define an outline of the first oxide semiconductor pattern, and the data line substantially defines an outline of the second oxide semiconductor pattern; forming a first insulation layer and a gate metal layer on the base substrate on which the source electrode, the drain electrode and the data line are disposed; patterning the gate metal layer on the first insulation layer to form a gate pattern comprising a gate electrode in the active region and a gate line in the wiring region, the gate electrode being disposed on the first insulation layer, the gate line being electrically connected to the gate electrode and extended in a direction crossing the data line; forming a second insulation layer on the base substrate on which the gate pattern is formed; forming a contact hole extending from the second insulation layer to expose a portion of drain electrode; forming a conductive layer on the second insulation layer and the portion of the drain electrode; and patterning the conductive layer to form a pixel electrode in the pixel portion such that the pixel electrode is electrically connected to the drain electrode through the contact hole.
