ABSTRACT:
A liquid crystal display device includes a substrate having a display region on which thin film transistors are formed and a pad region located in a periphery of the display region. The display region has a transparent electrode, the pad region has a pad electrode, and the transparent electrode and the pad electrode formed from a same layer. A barrier metal layer pattern is formed on the transparent electrode, and a reflective electrode is formed on the barrier metal layer. The reflective electrode has a transmission window for exposing a portion of the transparent electrode, wherein the barrier metal layer is comprised of material having an etching rate that is similar to an etching rate of the reflective electrode.
