1. An image display apparatus comprising:
an image forming element configured to form an original image; and a display optical system formed by an optical element whose inside surrounded by an entrance surface, multiple reflective surfaces and an exit surface is filled with an optical medium and configured to introduce a light flux from the original image to an exit pupil,wherein
wherein the display optical system is configured to:
cause the light flux entering from the original image by being transmitted through the entrance surface to reflect at a part of the reflective surfaces;cause the reflected light flux to form an intermediate image in the display optical system; andthen cause the light flux to reflect at another part of the reflective surfaces and exit from the exit surface toward the exit pupil located in a first direction, wherein the optical element comprises: a first optical portion on which the entrance surface and the part of the reflective surfaces are formed; a second optical portion that is provided in a second direction orthogonal to the first direction with respect to the first optical portion and on which the other part of the reflective surfaces and the exit surface are formed; and
a connection portion configured to be connected to a holding portion that is provided, as a different portion from the connection portion, for holding the optical element in the image display apparatus, and wherein:
the first optical portion has a side face in a width direction orthogonal to the first and second directions; andthe connection portion is formed on the side face so as to be included within a maximum width of the second optical portion in the width direction. |
