A projection-type image display apparatus includes an image display element, a light source unit, an enlarging projection optical unit, and a display controller portion. The enlarging projection optical unit, includes a projection lens, a group of lenses which are disposed on a same optical axis, sequentially arranged from a side of the image display element and which include at least one lens having a lens surface, and a reflection mirror having a reflection surface which is disposed between the group of lenses and a display portion. The image display element has a display surface larger than a display surface of the display portion, when an entirety of the image display element is enlargedly projected on the display portion through the enlarging projection optical unit; and the display controller portion enables movement of the image on the display surface of the image display element.
