Patent ID: 7450189

Claim:
A liquid crystal display device, comprising: a substrate of an in-plane switching liquid crystal display device having a display part and a non-display part; a gate line on the substrate; a common line substantially parallel to the gate line; a data line crossing the gate line and the common line while being insulated therefrom, to define a pixel area; at least one capacitor in the non-display part and connected to at least one of the gate line, the common line and the data line for storing a remaining electric charge component in the display part and eliminating the stored electric charge component; a common electrode in the display part of the substrate and connected to the common line; a thin film transistor at a crossing area of the gate line and the data line; a gate insulating film between the gate line and the data line; a protective film on the gate insulating film for protecting the thin film transistor; and a pixel electrode connected to the thin film transistor to form a horizontal electric field with the common electrode, wherein the component is a remaining electric charge component in the display part not induced from the outside, and wherein the capacitor includes: a first capacitor connected to at least one of the gate line and the common line; and a second capacitor connected to the data line, a first static electricity prevention means in the non-display part of the substrate and connected to the first capacitor; and a second static electricity prevention means in the non-display part of the substrate and connected to the second capacitor; wherein the first capacitor includes: a first shorting bar connected to the first static electricity prevention means; at least one layer of insulating film on the first shorting bar; and a first dummy line to overlap the first shorting bar on the at least one layer of insulating film.
