1. A manufacturing method of an array substrate, comprising:

  • forming, on a base substrate and via one patterning process, a transparent conductive pattern layer, a pattern layer including a pixel electrode, and a pattern layer including a gate electrode and a gate line, the transparent conductive pattern lying in a same level as the pixel electrode;

    on the substrate with the pattern layer including the gate electrode and the gate line formed thereon, through one patterning process or two patterning processes, forming a gate insulating layer, a pattern layer at least including a metal oxide semiconductor active layer and a pattern layer at least including an etch stop layer, wherein the etch stop layer comprises a first portion which is, along a gate line direction, between a second via hole and a third via hole that are located on two sided of the gate electrode;

    wherein, a first via hole for exposing the pixel electrode is formed over the pixel electrode; and

    on the substrate with the etch stop layer formed thereon, through one patterning process, forming a pattern layer including a source electrode, a drain electrode and a data line, wherein, the source electrode and the drain electrode each contact with the metal oxide semiconductor active layer, and the drain electrode and the pixel electrode are electrically connected through the first via hole.
