Patent ID: 7170573

Claim:
An array substrate for a transflective liquid crystal display device comprising: a substrate; a thin film transistor having a light-shielding layer deposited on the substrate, source and drain metal layers formed on an upper surface of the light-shielding layer, an ohmic contact layer deposited on each of upper surfaces of the source and drain metal layers, an amorphous silicon layer formed on the ohmic contact layer, an insulation layer formed on the entire surface of the amorphous silicon layer, and a gate metal layer formed on upper surfaces of the insulation layer and the amorphous silicon layer; a pixel region having an embossing light-shielding layer formed on the substrate, a corrugated reflection plate formed on an upper surface of the embossing light-shielding layer, and an insulation layer formed on an entire surface of the corrugated reflection plate; a gate pad having a light-shielding layer for the gate pad formed on an outer portion of an active region, an amorphous silicon layer formed on the light-shielding layer for the gate pad, an insulation layer formed on an entire surface of the amorphous silicon layer, and a gate metal layer formed on the amorphous silicon layer and the insulation layer; a source metal layer for a data pad formed at an outer portion of the active region; a protective layer formed on the gate metal layer of the thin film transistor and formed on an entire surface of the substrate formed on an upper surface of the gate metal layer for the gate pad; and a common electrode coated on a predetermined portion of the protective layer, in which the light-shielding layer of the thin film transistor, a pair of the corrugated reflection plate, the source metal layer for a data pad, and the light-shielding layer for the gate pad are not formed.
