PROBLEM TO BE SOLVED: To provide a display device equipped with a heat dissipation structure that securely discharges high-temperature air to the outside and is made low-cost by suppressing the number of components. SOLUTION: When a display panel 20 is in operation, heat of a heat generating component mounted on a power supply board 21 is conducted to air in a housing 2. Then, The air which becomes hot by high temperature rises by natural convection, and is discharged from an exhaust hole 12 on the upper surface of a back cabinet 4. Accordingly, external air flows in through an air intake 10 on the lower surface of the back cabinet 4 and presses up the air in the housing 2 from the bottom to the top to discharge the air, so the air in the housing 2 is prevented from reaching high temperature and forcible suction and exhaustion are carried out to eliminate the need for an air blowing fan, thereby eliminating unnecessary cost.
