A light blocking member that is a light blocking structure disposed in an exit pupil position can remove in advance a light component of video image light that undergoes unintended reflection to avoid generation of ghost light and allows formation of a satisfactory image. Further, a projection lens and other components form an intermediate image in a prism, and the video image light totally reflected off at least two surfaces of the prism, a third surface, a first surface, and a second surface in this order, passes through the first surface and reaches an eye of a viewer, whereby the prism can be thin and the overall optical system can be compact and lightweight and provide wide angle, bright, high-performance display. |
