<P>PROBLEM TO BE SOLVED: To provide a projection display device capable of preventing the reliability of a lamp cooling fan from being reduced by preventing the fan from being exposed to high temperature air and capable of reducing the temperature of exhaust air to the outside of the device. <P>SOLUTION: Since heat sinks 20, 21 are arranged between a lamp 1 and a cooling fan 26, air of which the temperature is increased by cooling the lamp 1 is sucked by the cooling fan 26 while the temperature is dropped by removing heat by the heat sinks 20, 21, so that the lamp cooling fan 26 is not exposed to high temperature air and the temperature of exhaust air from an exhaust duct 27 can be also dropped. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
