PROBLEM TO BE SOLVED: To provide a small type liquid crystal projector and a device wherein a liquid crystal, a polarizing plate, a PBS and a lamp are efficiently cooled by two fans and fan-noise is improved. SOLUTION: A first fan for exclusively cooling the G and B sides of a liquid crystal part and a second fan for cooling the R side of the liquid crystal part, the PBS and the lamp send air to the respective parts through one duct and have a suction hole and a filter in one part. Thereby, air can be sent to the G and B parts of the liquid crystal part, which have much light quantity even though a liquid crystal panel is a small type and has small gaps (between polarizing plates and the liquid crystal panel), with low rotation and air can be sent to the R side of the liquid crystal part, the PBS and the lamp from the same suction hole. |
