Abstract:
1. An array substrate for an LCD, comprising: a substrate having a transistor region and a storage capacitor region; a thin film transistor in the transistor region, comprising: a storage capacitor in the storage capacitor region, comprising: a planarization layer covering the thin film transistor and the storage capacitor; an interlayer dielectric layer between the planarization layer and the gate electrode and between the planarization layer and the upper electrode, wherein the interlayer dielectric layer above the upper electrode has an opening therein, such that the planarization layer contacts the upper electrode through the opening; and a pixel electrode disposed on the planarization layer and electrically connected to the source/drain electrode through the planarization layer; wherein the semiconductor layer and the transparent lower electrode are formed by the same polysilicon layer and the gate dielectric layer and the capacitor dielectric layer are formed by the same dielectric layer.
