An eyeglass-type image display device mounted on an eyeglass frame and has a display element for displaying an image and a light guiding unit for guiding the image light of the image displayed on the display elementis provided, wherein at least the light guiding unit is disposed on a limb unit so as to be displaceable to a first position where the light guiding unit is evacuated from the front of one eyeball of the user and to the second position where the light guiding unit extends to the front of the eyeball and the image light exits therethrough toward the eyeball, thereby enabling compact and light-weight structure, reduction in cost, and further enabling the user to wear the eyeglass frame for a long time without feeling that the eyeglass frame is heavy.
