Abstract
An electrostatic discharge protection circuit for liquid crystal displays. The liquid crystal display includes a plurality of crossing gate and data lines on a first substrate and a data shorting line and a gate shorting line. A plurality of first ESD protection units connect the gate shorting line to the gate lines, and a plurality of second ESD protection units connect the data shorting line to the data lines. Third ESD protection units connect the gate shorting line to the data shorting line. A common electrode is formed on a second substrate. A fourth ESD protection unit directly connects the common electrode to the data shorting line.
