A plasma display device includes: a Plasma Display Panel(PDP); a chassis base adapted to support the PDP attached to one surface thereof, a plurality of Integrated Circuit (IC) modules respectively included on driving circuit boards attached to another surface of the chassis base and adapted to control the PDP; and a reinforcing member arranged on the chassis base, one surface of each of the IC modules being in contact with the reinforcing member. The integrated circuit module is attached to the reinforcing member which reinforces the mechanical strength of the chassis base, so that a heat sink is not needed. The thickness of a plasma display device is thereby reduced and the appearance of the plasma display device is improved.
