ABSTRACT:
Disclosed are a liquid crystal display (LCD) device and a method for manufacturing the LCD device. The LCD device has a substrate including a display region and a pad region located in a periphery of the display region, the display region having a transparent electrode, the pad region having a pad electrode. The transparent electrode and the pad electrode are formed from the same layer. A reflective electrode having a transmission window exposing a portion of the transparent electrode is formed on the transparent electrode. The manufacturing process can be simplified because the transparent electrode is directly connected to the reflective electrode. Since the pad electrode is formed of the same layer as the transparent electrode, no metal corrosion occurs to thereby increase the pad reliability during COG bonding.
