ABSTRACT:
A multi-domain liquid crystal display device includes first and second substrates facing each other and a liquid crystal layer between the first and second substrates. A plurality of gate bus lines are arranged in a first direction on the first substrate and a plurality of data bus lines are arranged in a second direction on the first substrate to define a pixel region. A pixel electrode is electrically charged through the data bus line in the pixel region. A common-auxiliary electrode surrounds the pixel electrode on a same layer whereon the gate bus line is formed.
