ABSTRACT:
Disclosed is a liquid crystal display device having opaque electrodes at both edge portions of a pixel electrode. The LCD device includes a plurality of gate signal lines, each having a plurality of projected portions; a plurality of data signal lines, being perpendicular to the length direction of the gate signal line; a plurality of thin film transistors corresponding respectively to unit pixel region; a plurality of pixel electrodes formed on the insulating layer within respective unit pixel regions, being overlapped with the projected portion of the adjacent gate signal; and a plurality of opaque electrodes formed below said insulating layer, being arranged parallel to the data signal lines, each extending from both edge portions of each pixel electrode parallel to the data lines to selected positions between said each pixel electrode and both data lines adjacent thereto, each electrically connected with said each pixel electrode through a contact plug formed in said insulating layer.
