The plasma display device has an improved structural assembly that includes improved heat transfer interfaces between each of a chassis base and a PDP and a thermally conductive member interposed therebetween. The plasma display device may include a plasma display panel; a chassis base supporting the plasma display panel; a thermally conductive member disposed between the plasma display panel and the chassis base; a first adhesive layer formed between the plasma display panel and the thermally conductive member to adhere the plasma display panel and the thermally conductive member; and a second adhesive layer formed between the thermally conductive member and the chassis base to adhere the thermally conductive member and the chassis base. An adhesive strength of the first adhesive layer may be greater than an adhesive strength of the second adhesive layer.
