ABSTRACT:
A method for manufacturing a liquid crystal display device includes forming a gate pad on a substrate, forming an electrode and a data pad, forming a passivation layer on the electrode and data pad, etching the passivation layer to form first, second, and third contact holes for exposing the electrode, gate pad, and data pad, forming a transparent electrode and simultaneously forming a gate pad electrode and a data pad electrode connected to the gate pad and the data pad through the second and third contact holes, forming a barrier metal layer and a reflective layer on the transparent electrode and the pad electrodes, annealing the reflective layer for preventing lifting of the reflective layer, and patterning the reflective layer and the barrier metal layer to form a reflective electrode and a barrier metal layer pattern on the transparent electrode, wherein the barrier metal layer pattern and the reflective electrode are formed only on the transparent electrode excluding the first contact hole.
