Patent ID: 7349037

Claim:
A display device comprising: first and second substrates attached to each other with a cell gap there between; an image display unit containing a plurality of pixels arranged on the first substrate; a common electrode on the second substrate; a plurality of gate lines arranged on the first substrate in a horizontal direction and applying a gate low voltage and a gate high voltage to the image display unit; a plurality of data lines arranged on the first substrate in a vertical direction and applying image information to the image display unit; a common voltage line formed on the first substrate and applying a common voltage to the common electrode in the second substrate through the connecting member between the first and second substrates; a dummy gate line formed along an outer periphery region of the image display unit, the dummy gate line configured to substantially maintain only gate low voltage; first electrostatic preventing units respectively connected to one side of the gate lines and commonly connected to the dummy gate line at another side of the first electrostatic preventing units; second electrostatic preventing units respectively connected to one side of the data lines and commonly connected to the common voltage line; and third electrostatic preventing units connecting the first gate line and the common voltage line.
