Abstract:
1. A method of fabricating an array substrate for a transflective liquid crystal display device, comprising: forming a gate line and a data line on a substrate, the gate line and the data line crossing each other to define a pixel region including a transmissive area and a reflective area surrounding the transmissive area; forming a gate insulating layer between the gate line and the data line; forming a thin film transistor connected to the gate line and the data line; forming a first passivation layer on the thin film transistor, the first passivation layer having a drain contact hole exposing a drain electrode of the thin film transistor and a through hole exposing the gate insulating layer on the substrate in the transmissive area; sequentially forming a first metal layer, a first inorganic insulating material layer and a first photoresist pattern on the first passivation layer; etching the first metal layer, the first inorganic insulating material layer and the gate insulating layer using the first photoresist pattern as an etch mask to form a reflective plate and a second passivation layer on the reflective plate and to expose the drain electrode through the drain contact hole and the substrate through the through hole; and forming a pixel electrode on the second passivation layer, the pixel electrode contacting the drain electrode through the drain contact hole.
