Abstract
A liquid crystal projector includes a light modulating device, a cooling device, a dehumidification device, and a housing. The light modulating device forms an optical image by modulating light flux emitted from a light source based on image information. The cooling device cools air to be supplied to the light modulating device. The dehumidification device dehumidifies and dries air to be supplied to the corresponding cooling device. The housing includes a cooling medium flow path for circulating air among the light modulating device, the cooling device, and the dehumidification device. The cooling device includes a thermoelectric conversion material interposed between a pair of heat transmission plates arranged to face each other.
