ABSTRACT:
Disclosed is a liquid crystal display device comprising a pair of facing substrates; a plurality of thin film transistors formed on one of the facing substrates; a plurality of pixel electrodes driven according to the actuation of the thin film transistors. The present invention provides a liquid crystal display device comprising a lower substrate; a plurality of gate bus lines formed on the lower substrate and to which selecting signals are applied parallel to each other; a plurality of common electrodes formed on the lower substrate; a plurality of thin film transistors connected to the gate bus lines and the common electrodes respectively; a plurality of pixel electrodes formed on the lower substrate and to which voltage signals from the common electrodes are applied in accordance with action of the thin film transistors; an upper substrate disposed oppositely to the lower substrate; a plurality of data bus lines formed on the upper substrate parallel to each other and to which image signals are applied; a plurality of color filters formed on the upper substrate above the data bus lines; and a plurality of transparent electrodes arranged on top of the color filters such that they are in contact with the data bus lines.
