摘要：An embodiment of the invention relates to a TFT-LCD array substrate comprising a substrate, a gate line and a data line formed on the substrate, a pixel electrode and a thin film transistor formed in a pixel region defined by the gate line and the data line, wherein the thin film transistor comprises a gate electrode, a source electrode, and a transparent drain electrode, and the transparent drain electrode is electrically connected with the pixel electrode.

主权项：1. A manufacturing method of a thin film transistor liquid crystal display (TFT-LCD) array substrate, comprising: Step 1, depositing a gate metal film on a substrate and forming patterns including a gate line and a gate electrode by a patterning process; Step 2, forming patterns including an active layer, a data line, a source electrode and a passivation layer via hole in a passivation layer with on the substrate after step 1, wherein the passivation layer via hole exposes the surface of the active layer in the drain electrode region; and Step 3, depositing a transparent conductive film on the substrate after step 2 and forming patterns of a transparent drain electrode and a pixel electrode which are in an integral structure and connected with each other.
