Abstract
A heat dissipation member is disposed opposing a reflective light modulation element, and includes: a heat receiving surface that receives heat from the element; a heat dissipation surface; and heat dissipation fins that protrude from the heat dissipation surface. The fins are formed so that the density at which the fins are disposed is greater at the center area of the heat dissipation surface than at the end areas of the heat dissipation surface, or are formed so that the cross-sectional surface area of the fins is greater at the center area of the heat dissipation surface than at the end areas of the heat dissipation surface.
