A plasma display device is provided to radiate effectively heat from a circuit element by covering an outer circumference of the circuit element with a heat-radiating plate of a heat-sink and protruding a plurality of radiating fins from the heat-radiating plate. A chassis base(20) is coupled with one side of a plasma display panel(10). A printed circuit board assembly(30) is coupled with the chassis base in order to control the plasma display panel. The printed circuit board assembly includes a circuit element formed on a printed circuit board in order to drive the plasma display panel and a heat-sink(60) installed at the circuit element. The heat-sink includes a heat-radiating plate and a plurality of heat-radiating fins protruded from an outer circumference of the circuit element. Two or more heat-sinks are formed to cover outer circumference of the circuit element. The heat-sinks have different heights to form an aperture for opening a part of a lateral surface of the circuit element. |
