A display device heat dissipating panel. A chassis is provided that has improved heat transferring characteristics as well as sufficient structural integrity, thereby decreasing the temperature in a front portion of the PDP. A plasma display panel that is attached to a chassis base. A driving circuit which drives the plasma display panel is mounted to the chassis base. The chassis base includes a first plate to which the plasma display panel is attached. A second plate is disposed to face the first plate and is adjacent to the first plate, the driving circuit being mounted to the second plate. A reinforcing member is disposed between the first plate and the second plate and connects the first and second plates.
