Abstract:
1. A liquid crystal display device, comprising: a plurality of gate lines being driven by a gate driving circuit; a dummy gate line receiving only a gate low voltage; a liquid crystal display panel, the liquid crystal display panel comprising a non-display area; a signal terminal receiving the gate low voltage; a first signal line arranged in the non-display area, the first signal line connected to the signal terminal for supplying the gate low voltage; a second signal line arranged in the non-display area, the second signal line connected between the dummy gate line and the first signal line for supplying the gate low voltage, and a common voltage line, wherein the plurality of gate lines are connected to the first signal line and the common voltage line via a plurality of static electricity prevention circuits, and the dummy gate line being connected to the common voltage line via the static electricity prevention circuit is connected to the gate lines in parallel to minimize a gate low voltage difference between the dummy gate line and the gate lines.
