ABSTRACT:
A projection type image display apparatus includes a lens group, being disposed adjacent to an image display element, which is configured to include a plural number of lenses, and a mirror, which is configured to reflect emission lights from the lens group, so as to project upon the screen obliquely. A ratio (Lo/Lp) between a distance (Lp) from a center of the mirror up to the screen and a diagonal size (Lo) of the screen is at least 2.
