Abstract
A projection type display apparatus includes a projection lens barrel holding a projection lens, a micro mirror type display element, and a main body which holds the micro mirror type display element and on which the projection lens barrel is mounted. The projection lens barrel is formed with a barrel-side reference surface which becomes a mounting reference in a direction of an optical axis, and the main body is formed with a mounting reference surface against which the barrel-side reference surface abuts. The main body has an adjusting mechanism which adjusts a length between a reflection surface of the micro mirror type display element and the mounting reference surface.
