Abstract

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.
