Abstract
An image display apparatus has a first exhaust fan () for mainly exhausting air from a light source unit () and discharging the air to the outside of the image display apparatus and a second exhaust fan () for mainly exhausting air from a power supply unit () and discharging the air to the outside of said image display apparatus. The inspiration face of the second exhaust fan is arranged to partly overlap the expiration face of the first exhaust fan. Accordingly, the internal temperature of the image display apparatus, and hence the temperature of the exhaust air, can be efficiently reduced, and at the same time fan noise of the fans can be reduced. As a result, uprating of power of the light source unit and downsizing of an image display apparatus can be simultaneously achieved.
