A plasma display is provided with a plasma display panel, data drivers which apply data pulse to data electrodes of the plasma display panel, a control circuit which t controls an operation of the data drivers based on a video signal, and a protection signal output circuit. The protection signal output circuit outputs a protection signal to the control circuit when sum of currents supplied from the data drivers to the data electrodes within a time equal to one sub-field or more to less than one frame exceeds a previously set first specified current value. The protection signal restrains the operation of the data drivers.
