摘要： A projector includes: spatial light modulation devices; and a cooling duct configured to flow a cooling air for sequentially cooling the spatial light modulation devices, the cooling duct has a first flow path formed by portions including the light entrance surface of at least one of the spatial light modulation devices for the respective color lights, a second flow path formed by portions including the light exit surface of the corresponding spatial light modulation device, and a junction area where the cooling air flowing through the first flow path and the cooling air flowing through the second flow path join each other, and the junction area is disposed at a downstream position of the cooling air with respect to the spatial light modulation device provided for a predetermined color light whose light amount is the maximum in the respective color lights that enter the light entrance surface.
