Image displaying apparatus

An image displaying apparatus comprising:

• an image displaying element configured to form an image to be projected;
• and
• a projection optical system having a positive refractive power and configured to project the image to be projected onto a screen,
• wherein the projection optical system includes a lens optical system and a mirror optical system, the lens optical system including plural lens groups, the mirror optical system including a first mirror and a second mirror, the second mirror being a concave mirror,
• wherein an intermediate image of a pixel of the image displaying element is formed between the image displaying element and the second mirror,
• wherein the first mirror is held by a position adjusting part which adjusts a position thereof, the position adjusting part including a plurality of spacers which are inserted between a back face of the first mirror and a back supporting part, the position of the first mirror being adjusted by a thickness of each of the spacers, and
• wherein the thicknesses of the spacers are different from one another and the first mirror is held to be capable of adjusting a tilt of a reflection surface thereof.
