An electrostatic discharge (ESD) protection circuit ( 140 ) includes: a first transistor ( 141 ), a second transistor ( 142 ), a third transistor ( 143 ), and a fourth transistor ( 144 ). Each transistor includes a source electrode 's', a drain electrode 'd' and a gate electrode 'g'. The gate electrode 'g' of the first transistor, the gate electrode 'g' of the second transistor, the drain electrode 'd' of the third transistor, and the drain electrode 'd' of the fourth transistor are connected to each other. The source electrode 's' of the first transistor, the source electrode 's' of the second transistor, and the source and gate electrodes of the third transistor are connected to each other. The drain electrode 'd' of the first transistor, the drain electrode 'd' of the second transistor, and the source and gate electrodes of the fourth transistor are connected to each other.
