Provided is a rear projection type display apparatus having a structure capable of performing projection magnification correction with a small depth. A projection unit is mounted on a projection magnification correcting member, and the projection magnification correcting member includes a first member and a second member. The first member includes a first correction mechanism for correction in a direction parallel to a central light ray, and is supported by a housing. The second member includes a second correction mechanism for correction in a direction parallel to a normal line to an image plane enlarged and projected from the projection unit without passing through a reflection mirror, and is supported by the first member.
