Abstract
An intake opening ( L) is formed on a left lateral side ( ) of a lower cabinet ( ) and an exhaust opening ( R) is formed on a right lateral side ( ) in a rear projector ( ), where a cooling air introduced from the intake opening ( L) by a plurality of fans provided in the lower cabinet ( ) flows along a front side of a screen to cool the interior of the projector to be finally discharged from the exhaust opening ( R), so that the air after cooling the interior which is discharged by the exhaust opening ( R) is prevented from entering into the intake opening ( L), thereby always introducing fresh cooling air to cool the interior efficiently.
