Electro-optical device encased in mounting case, projection display apparatus, and mounting case

摘要

The invention provides a technique to effectively cool an electro-optical device in the electro-optical device encased in a mounting case. The mounting case can include a plate member arranged so as to face one surface of a liquid crystal panel and a cover member arranged so as to cover the plate and the liquid crystal panel. Cooling-air guiding portions that include at least some of the side surfaces of the liquid crystal panel as at least some of the surfaces that constitute the passage can be provided in the cover member.
