This invention relates to a transflective LCD device using different common voltages in the transmissive and reflective regions to present the same gray scale performance on the transmissive and reflective regions. The liquid crystal display device includes a first substrate including a plurality of transmissive regions and a plurality of reflective regions; a transmissive electrode formed on said transmission electrode region; a reflective electrode formed on said reflective regions and connected electrically with said transmissive electrode; a second substrate including a plurality of first common electrodes and a plurality of second common electrodes, wherein said first common electrodes are formed over said transmissive regions, said second common electrodes are formed over said reflective regions, and said first common electrodes are not connected electrically with said second common electrodes; and a liquid crystal layer interposed between said first substrate and said second substrate.
