ABSTRACT:
An image observation device includes a two-dimensional image display element, a relay optical system for forming a real image of an image displayed on the two-dimensional image display element, an eyepiece optical system for forming a magnified image of the real image and bending the optical axis, and a supporting member for supporting the eyepiece optical system to be located directly before the eyes of the user. This arrangement makes it possible to provide the image observation device which is small in size and high in magnification for observation.
