A packaging case-encased electro-optical device includes: an electro-optical device where projection light from a light source enters an image display area, a dust-proof substrate disposed on a light incident plane or a light emitting plane thereof, a first light blocking film disposed thereon, a second light blocking film formed on an counter substrate configuring the electro-optical device, and a packaging case to house the electro-optical device and the dust-proof substrate. The second light blocking film, the first light blocking film, the dust-proof substrate and the packaging case configure a heat conducting path.
