A heat radiating assembly employable by a plasma display apparatus for radiating heat generated by a signal transmission unit, which transmits electric signals from a circuit unit that drives a plasma display panel and includes an electronic device covered by a protecting member, is provided. The heat radiating assembly may include a heat absorbing member, a heat radiating member, and a heat transferring member. The heat absorbing member may absorb the heat generated by the electronic device and transmitted to the protecting member. The heat radiating member may radiate heat out from the plasma display apparatus. The heat transferring member may transfer the heat from the heat absorbing member to the heat radiating member.
