Abstract
It is possible to display high quality images by reducing or preventing heat accumulation in an electro-optical device, reducing or preventing undesired force from being applied to the electro-optical device due to the expansion and contraction of a mounting case, and reducing or preventing dislocation of the electro-optical device in the mounting case. The electro-optical device having an image display region, on which projection light from a light source is incident light, is encased in the mounting case constituted of a plate and a cover. One of the plate and the cover includes a resin member to fix the electro-optical device to the mounting case and a metal member including a window corresponding to the image display region in the electro-optical device.
