ABSTRACT:
A display apparatus includes a light source, plural reflecting type light valves having a light incidence/reflection surface which reflects incident light from the light source, and a partition wall which partitions a space in the display apparatus into a cooling air side and a light incidence/reflection surface side. Plural cooling fans which cause air flow to respective ones of the light valves, and a discharge fan which discharges a cooling air inside of the display apparatus through an outlet port are provided. A respective one of the cooling fans flows air to a side which is opposite to the incidence/reflection surface of a respective one of the light valves and a path of the air flow is formed from at least one of the cooling fans to the outlet port in an order of the opposite side of the light valve, the light source and the discharge fan.
