PROBLEM TO BE SOLVED: To suppress a rise in temperature of a power supply module of a plasma display device. SOLUTION: A plasma display device includes a panel unit 10 and the power supply module 12, which is disposed leaving a space with the panel unit 10 and has a heat-radiating unit 11 on the reverse surface, and the heat radiation unit 11, faces the panel unit 10 and has a heat-reflecting layer 22 formed on the surface facing the panel unit 10, wherein the heat-reflecting layer 22 is formed of a material of far-infrared ray reflectivity at a wavelength of 8l.0 to 9.0μm larger than that of the main body of the heat radiation unit 11. Consequently, far-infrared rays emitted from the panel unit 10 can be reflected by the surface of the heat radiation unit 11 opposing the panel unit 10, and consequently, the rise in temperature of the power supply module 12 of the plasma display device 9 can be suppressed.
