Abstract
A display apparatus includes a light source, a reflecting type light valve having a light incidence/reflection surface which reflects incident light from the light source, a first cooling fan which cools the reflecting type light valve, and a second cooling fan which cools the light source. A part of the display apparatus which is opposite to the light incidence/reflection surface of the reflecting type light valve is cooled by a cooling fluid generated by the first cooling fan.
