A display device that can prevent the thermal destruction and screen burn-in caused by display patterns has been disclosed. In this device, the display luminance is determined by the number of light emissions, and there are provided a sustain frequency control section that controls the sustain frequency, a load ratio calculation section that calculates the load ratio for each frame of display data, plural counters, a load ratio counter control section that controls so as to increase the counts of the counters corresponding to the load ratio level calculated by the load ratio calculation section, and a first judgment section that outputs a first control signal when any of the counts exceeds a first reference value, wherein the sustain frequency control section decreases the sustain frequency according to the first control signal.
