The invention provides a display device designed to reliably discharge air heated to a high temperature to the outside. Heat from a heating part mounted on a power supply substrate is transmitted to air inside an enclosure and the air heated to a high temperature moves upward by means of natural convection and is discharged through exhaust holes in the upper surface of a back cabinet. As a result of this, outside air is taken in through intake holes in the lower surface of the back cabinet, the outside air pushes up the air inside the enclosure from below and discharges it, and it is possible to thereby prevent the air inside the enclosure from becoming hot and forcibly take in/exhaust air, eliminate the necessity for any air blowing fan and thereby achieve cost reduction.
