Abstract:
1. A method of manufacturing a thin film transistor liquid crystal display (TFT-LCD) array substrate, comprising: forming a gate line and a gate electrode on a base substrate and then depositing a gate insulating layer on the base substrate; forming an active layer, a data line, a source electrode, and a drain electrode on the gate insulating layer and removing the gate insulating layer in the region other than the regions of the active layer, the data line, the source electrode and the drain electrode; forming a photosensitive resin layer on the base substrate formed with the above patterns, and forming a first via hole, a second via hole and a third via hole in the photoresist layer by an exposing and developing process, wherein the first via hole is provided in a gate pad region, the second via hole is provided in a data pad region, and the third via hole is provided at the drain electrode; and forming a pixel electrode, a first connection electrode and a second connection electrode on the photosensitive resin layer, wherein the first connection electrode is connected with the gate line through the first via hole, the second connection electrode is connected with the data line through the second via hole, and the pixel electrode is connected with the drain electrode through the third via hole.
