An electrostatic discharge protection network for large area transducerarrays in which each transducer has associated therewith an addressing circuit for changing the state of the transducer element. Each addressing circuit includes at least one thin film transistor having a resistive path provided between the thin film transistor gate electrode and one or both of the transistor's other two terminal electrodes in order to provide current leakage paths for equalizing the potential between the gate electrode and the other two terminals during an electrostatic discharge.
