Abstract
A projection device includes: a plate shaped member that is thermally conductive; a light emitting element that is disposed upon the plate shaped member and emits light; a bending member that bends light from the light emitting element into an orientation parallel to the plate shaped member; a modulation element that modulates light bent by the bending member; and a polarized light separation element that bends light modulated by the modulation element into an orientation going away from the plate shaped member.

A projection device, comprising:
- a plate shaped member that is thermally conductive;
- a light emitting element that is disposed upon the plate shaped member and emits light;
- a bending member that bends light from the light emitting element into an orientation parallel to the plate shaped member;
- a modulation element that modulates light bent by the bending member;
- and
- a polarized light separation element that bends light modulated by the modulation element into an orientation going away from the plate shaped member.

A projection device, comprising:
- a member that is thermally conductive, and that has two surfaces that mutually intersect;
- a light emitting element that is provided upon one of the surfaces of the member, and that emits light in an orientation parallel to the other surface of the member;
- a modulation element that modulates light from the light emitting element;
- and
- a polarized light separation element that bends light modulated by the modulation element into an orientation going away from the other surface of the member.
