Abstract
In a virtual image display device, since the frame section has the support section for detachably fixing the auxiliary mounting member, which is disposed adjacent to the optical members, on the observer side of the optical members, by providing a variety of functions such as an optical function to the auxiliary mounting member, the usefulness of the virtual image display device can be enhanced. Specifically, in the case of, for example, providing the auxiliary mounting member with a diopter correction function, it is possible for any observers with a variety of levels of vision to observe the image obtained by the video display element in a good condition without blur without using eyeglasses.
