An array substrate for a transflective liquid crystal display device includes a plurality of gate lines and a plurality of data lines disposed on a substrate and crossing each other to define a plurality of pixel regions, a thin film transistor adjacent to each crossing of the gate and data lines, a passivation layer covering the thin film transistor, a reflector in each pixel region and having an opening, the reflector overlapping the gate and data lines with an overlap width, and a transparent electrode in each pixel region and shifted in a first direction with respect to the reflector.
