A plasma display device entirely distributes the temperature of a heat generator, and improves the detachability of a heat dissipating sheet and coherence with the heat generator. The plasma display device includes a plasma display panel for displaying an image, a chassis base disposed to face the plasma display panel, and a heat dissipating sheet disposed between the plasma display panel and the chassis base and including a resin material and carbon fibers fixed in the resin material. Preferably, the carbon fibers are intensively impregnated in a center portion of the resin material toward the display panel, and are arranged at least in one direction parallel to the display panel, or in different directions with respect to each other and separated from each other by the resin material.
