摘要： PROBLEM TO BE SOLVED: To sufficiently dissipate heat of a heat generating part in a sustain circuit of a plasma display device, and to enhance the performance of the sustain circuit that handles fast and large current pulses. SOLUTION: A heat pipe 103 is used so that a heat generating part 102 and a radiation fin 104 that is a heat dissipating part can be arranged separately. By arranging structural members, the heat dissipating part can be positioned at the center of the screen and the like allowing the physical thickness of the heat dissipating part. Thus, an operator does not feel, when handling a device, that the device is thick and, in addition, the occurrence of failures such as noises due to the increase in wiring length is prevented.
