Abstract:
1. A method for fabricating an array substrate for a liquid crystal display (LCD), comprising: providing a substrate having a transistor region and a storage capacitor region; forming a semiconductor layer and a transparent lower electrode on the transistor region and the storage capacitor region of the substrate, respectively; covering the semiconductor layer and a transparent lower electrode by a first dielectric layer to serves as a gate dielectric layer in the transistor region and a capacitor dielectric layer in the storage capacitor region; forming a gate electrode and an upper electrode on the first dielectric layer in the transistor region and the storage capacitor region, respectively, wherein the upper electrode comprises a transparent electrode portion and a metal electrode portion; forming a second dielectric layer on the first dielectric layer and covering the gate electrode and the upper electrode; forming a source/drain electrode on the second dielectric layer in the transistor region, electrically connected to the semiconductor layer through the first and second dielectric layers; forming a planarization layer on the second dielectric layer; and forming a pixel electrode on the planarization layer, electrically connected to the source/drain electrode through the planarization layer.
