A liquid crystal display device includes a gate electrode formed on an upper surface of an insulating substrate, a gate insulating film laminated to cover the gate electrode, a drain electrode and a source electrode formed above the gate insulating film, a semiconductor layer laminated on an upper surface of the gate insulating film, and controlling a current between the source electrode and the drain electrode by an electric field developed by the gate electrode, a common electrode having an opening portion which is formed in a region corresponding to a channel region above the semiconductor layer, and an antistatic pattern arranged at a distance from the drain electrode and the source electrode. One end and the other end of the antistatic pattern are coupled to the common electrode.
