  • a first member constituted of a thermally conductive material, at which a light emitting device is disposed;

    a light modulating member that modulates light originating from the light emitting device;

    a projection optical system that projects an image formed with the light modulated by the light modulating member;

    a second member constituted of a material with a lower level of thermal conductivity compared to the first member, at which the first member and the light modulating member are disposed; and

    a third member constituted of a material with a high level of thermal conductivity compared to the second member, that supports the second member and the projection optical system as an integrated unit and comes into surface contact with the first member.
