Abstract: A liquid crystal display device including a cut portion at a position not overlapping the gate electrode such the pixel electrode is floating and does not receive a voltage from the source electrode via the active layer and the drain electrode; a second insulating layer above the first insulating layer; a plurality of common electrodes on the second insulating layer; and a welded portion at a region where a corresponding common electrode overlaps the drain electrode. Further, the drain electrode and the pixel electrode are electrically connected to each other via a connection pattern formed in a contact hole such that the welded portion floats the pixel electrode.
