摘要： In an LCD projector or other projection type display apparatus which uses a lamp such as a xenon lamp for a light source, the lamp is cooled efficiently without increasing ambient noises or without causing the whole apparatus to become large-sized, and at the same time the lifetime and the reliability of a fan which cools the lamp is made improved. When fans 3 and 4 which are disposed on a front side of the lamp mounted with a heat sink 1 rotate, external air of ordinary temperature is taken in from an inlet and guided into ducts 5 and 6 so as to be blown onto the front face of the lamp by means of the fans 3 and 4. Then, high temperature air which was warmed by being blown onto the lamp is exhausted from an outlet to the outside.

摘要： A liquid crystal display device constrains the injection of air bubbles in a cooling fluid into a display panel. In the display device, the cooling fluid is supplied to a receiving space of a receiving unit placed and opposed to a surface of a liquid crystal panel to which the light is emitted from a light source to thereby cool the liquid crystal panel. Namely, by a cooling fluid pump, the cooling fluid received in the receiving unit is drained from a drain port and the cooling fluid is supplied from a feed port to the receiving unit and received in the receiving space. In the above case, a part of a flow path of the cooling fluid supplied from the feed port is blocked by a flow path block unit placed and opposed to the feed port to thereby disperse the flow thereof around the flow path block unit.
