| 1. A display device comprising:
an image creating unit which creates a predetermined color component to light from a light source;
a spatially modulating unit which modulates the light, including the predetermined color component provided by the image creating
unit, according to an image signal;
a projecting unit which projects the light modulated by the spatially modulating unit, to a predetermined position;
a uniformalizing unit which uniformalizes the in-plane intensity of light input into the image creating unit;
a guiding member which guides air guided to the spatially modulating unit is to the image creating unit and the uniformalizing
unit;
a first fan which takes in air from the outside and feeds it into the spatially modulating unit; and
a second fan which delivers the air taken in by the first fan and guided through the guiding member, to the outside.
