ABSTRACT:
A LCD device includes substrates attached to each other with a cell gap therebetween. An image display unit is composed of pixels arranged on the first substrate, for substantially displaying an image. Gate lines are arranged in a horizontal direction, for applying a gate low voltage and a gate high voltage to the image display unit. Data lines are arranged in a vertical direction, for applying image information to the image display unit. A common voltage line applies a common voltage. First electrostatic preventing units are respectively connected to one side of the data lines and commonly connected to a first gate line. Second electrostatic preventing units are respectively connected to one side of the gate lines and commonly connected to the common voltage line. Third electrostatic preventing units connect the first gate line and the common voltage line.
