PURPOSE: A heat spreader for display device is provided to a production cost generated from expanding process by directly using natural graphite and to prevent environment pollution and to prevent generation of a short circuit beforehand by preventing generation of a conductive particle. CONSTITUTION: A heat spreader for display device comprises: a heat diffusion layer including a graphite and a thermoplastic resin; a first tackifier layer formed on top of the heat diffusion layer; a metal layer(10) formed on top of the first tackifier; a second tackifier layer(12) formed on the metal layer. The metal layer comprises copper and aluminum or zinc plated steel sheet. A electromagnetic wave-blocking layer(14) is located between the metal layer and the tackifier layer. |
