1. A liquid crystal display device of a gate-in-panel structure comprising:
a liquid crystal display panel with an active area used to display images; a gate driving circuit formed on a side edge of the liquid crystal display panel and configured to apply scan signals to the active area; a start pulse line configured to transfer a start pulse to the gate driving circuit; and a static electricity preventer disposed on the start pulse line adjacent to the gate driving circuit and configured to prevent static electricity from being induced in the start pulse line, wherein the static electricity preventer includes a static electricity prevention capacitor configured to include lower and upper electrodes opposite to each other in the center of a dielectric film; wherein the upper electrode is connected to a voltage line via another line in a layer different from that of the upper electrode, the voltage line is configured to transfer a low level driving voltage to the gate driving circuit, the upper electrode is formed from the same material as a pixel electrode within the active area, and the upper electrode is disposed in the same layer as the pixel electrode; wherein the lower electrode is an expansion of the start pulse line in a width direction, a width of the lower electrode being greater than a width of the start pulse line in plan view; and wherein the lower electrode and the upper electrode each have a rectangular shape, the rectangular shapes overlapping in plan view.
