PROBLEM TO BE SOLVED: To provide a rear projector with improved cooling efficiency of the housing inside. SOLUTION: An air inlet port 111 and an air discharge port 118 are provided on the rear side of a lower housing 104 of the rear projector. The lower end of the discharge port 118 is disposed on the same line as the upper end of the inlet port 111 or above the upper end of the inlet port 111. Furthermore, when the discharge port 118 is disposed on the right side of the inlet port 111, the left end of the discharge port 118 is disposed on the same line as the right end of the inlet port 111 or on the right side of the right end of the inlet port 111. When the discharge port 118 is disposed on the left side of the inlet port 111, the right end of the discharge port 118 is disposed on the same line as the left end of the inlet port 111 or on the left side of the left end of the inlet port 111. Thereby, influence of the exhaust air on the intake is reduced. COPYRIGHT: (C)2008,JPO&INPIT
