Patent ID: 7098982

Claim:
A liquid crystal display device comprising: first and second substrates; a liquid crystal layer interposed between the first and the second substrates; a plurality of scanning signal lines and a plurality of data signal lines which are formed on the first substrate, and common signal lines which are arranged close to the scanning signal lines; wherein each unit pixel, which is formed as a region surrounded by adjacent scanning signal lines and adjacent data signal lines, includes a pixel electrode to which signals of the data signal line is electrically supplied through a thin film transistor and a common electrode which is electrically connected with the common signal line; wherein the common electrode is arranged to be superposed on the common signal line by way of an insulation layer, and the pixel electrode is electrically connected with a source electrode of the thin film transistor via a through hole which penetrates the insulation layer; wherein a portion of the pixel electrode includes an overhanging portion which overhangs above the common signal line from the unit pixel; and wherein the source electrode includes a projecting portion and the projecting portion is superposed on the overhanging portion of the pixel electrode and is formed in a direction which faces the overhanging portion in an opposed manner.
