摘要：
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.
