Abstract
An electronic image display panel is a reflective liquid crystal panel. With respect to the surface of the electronic image display panel, an optical axis of an eyepiece lens is perpendicular. The optical axis passes through a central part of the electronic image display panel that is a main observation point of an observer. When observing the electronic image display panel, a visual axis of an eye of the observer forms no large angle with respect to the electronic image display panel and the observer can stereoscopically observe electronic images displayed on the electronic image display panels at an original binocular parallax provided by an objective lens of a surgical microscope. As a result, the observer feels no eye fatigue or headache even when observing the images for a long time.
