An array substrate for a transflective liquid crystal display device includes: a substrate; a gate line and a data line on the 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; a thin film transistor having a gate insulating layer, the thin film transistor connected to the gate line and the data line; 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 substrate in the transmissive area; a reflective plate on the first passivation layer; a second passivation layer on the reflective plate; and a pixel electrode on the second passivation layer, the pixel electrode contacting the substrate in the transmissive area through the through hole and contacting the drain electrode through the drain contact hole.
