A display device such as a PDP that can prevent thermal destruction or screen burn-in caused by display patterns. In this device, the display luminance is determined by the number of light emissions, and there are provided a sustain frequency control section (26) that controls the sustain frequency, a load ratio calculation section (22) that calculates the load ratio for each frame of display data, plural counters (32-1...32-N), a load ratio counter control section (31) that controls so as to increase the counts of the counters corresponding to the load ratio level calculated by the load ratio calculation section (22), and a first judgment section (33) that outputs a first control signal when any of the counts exceeds a first reference value, wherein the sustain frequency control section (26) decreases the sustain frequency according to the first control signal. |
