Image display apparatus

An image display apparatus comprising:

• a light source;
• a scanning member for deflecting a light from said light source to scan a predetermined surface with the light to form a two-dimensional image thereon;
• a first optical system for guiding the light deflected by the scanning member onto the predetermined surface, the first optical system having, on an optical path, an optical element with a plurality of optical surfaces including a refractive surface and a reflective surface formed on a same medium, the light deflected by the scanning member is guided to the predetermined surface through the reflective surface of the optical element;
• and
• a second optical system for guiding the light from the two-dimensional image formed on the predetermined surface to an observer, the second optical system having the optical element on the optical path,
• wherein the first optical system and second optical system share a part of optical surfaces of said optical element.
