Abstract:
1. A TFT LCD array substrate, comprising: a substrate and a pixel array on the substrate, each pixel comprising: a gate line and a gate electrode connected with the gate line formed on the substrate; a gate insulating layer formed on the gate electrode and a semiconductor layer formed on the gate insulating layer; and an isolating dielectric layer covering the substrate, the gate line, the gate electrode, the gate insulating layer and the semiconductor layer, wherein via holes, in which an ohmic contact layer is deposited, are formed in the isolating dielectric layer over both sides of the semiconductor layer, a transparent pixel electrode formed on the isolating dielectric layer and establishing an ohmic contact with the semiconductor layer via the ohmic contact layer in the via holes, and a source electrode, a drain electrode and a data line, which are formed on the transparent pixel electrode.
