Abstract
A display apparatus having a reflecting type light valve which has a light incidence/reflection surface, a drive circuit which drives the reflecting type light valve by supplying an image signal, a cooling system which cools at least the reflecting type light valve with cooling fluid, and a partition wall which partitions a space in the display apparatus into a cooling fluid side and a light incidence/reflection side. The reflecting type light valve forms a part of the partition wall, and the light incidence/reflection surface faces the light incidence/reflection side and a part opposite to the light incidence/reflection surface of the reflecting type light valve is cooled by the cooling system.
