5. A liquid crystal display device comprising:
a pair of substrates placed oppositely at a certain distance away from each other;
a liquid crystal layer placed between the substrates;
a gate line and a source line formed on one of the substrates, the gate line and the source line crossing each other;
a switching element connected to the gate line and the source line;
a comb-shaped pixel electrode connected to the switching element, the pixel electrode having a plurality of electrodes substantially parallel to the source line; and
a comb-shaped common electrode connected to the switching element, the common electrode having a plurality of electrodes parallel to and alternating with the plurality of electrodes of the pixel electrode,
wherein an electric field substantially parallel to the substrates is applied to the liquid crystal layer by a voltage applied across the pixel electrode and the common electrode, and a position where at least a part of side surfaces of the source line and a semiconductor layer of the switching element are aligned in a vertical direction is not on an area where the source line is overlapped with the common electrode.
