Abstract
A projector includes an enclosing structure that encloses an optical path from an electrooptical device to a projection lens with a heat insulating member, and a thermoelectric transducer for cooling air inside the enclosing structure. Since the enclosing structure is formed by the heat insulating member, the electrooptical device can be efficiently cooled while thermally blocking between the inside and the outside thereof. Since being enclosed, the entry of dust or oil mist from the outside is prevented, and dust or oil mist does not adhere to the electrooptical device and the like.
