ABSTRACT:
The electrostatic discharge (ESD) protection device for a liquid crystal display using a chip on glass (COG) package is provided. The ESD protection device includes a plurality of gate lines and data lines each of which has an output pad at its end. A plurality of gate line input pads and data line input pads are formed opposite to the output pads of the gate lines and data lines, respectively. A common electrode is formed between the plurality of gate line input pads and output pads and between the data line input pads and output pads. A plurality of electrostatic discharge protection circuits are connected between the input pads and the common electrodes to protect the input pads from electrostatic discharge.
