Abstract
A first light blocking portion and a second light blocking portion are formed in at least one of the side surfaces of a light guide prism. The first light blocking portion and the second light blocking portion are arranged so that a shaded area and an invisible area overlap each other at least partly and cover an inter-groove area between the first light blocking portion and the second light blocking portion, where the shaded area is an area shadowed from image light due to the first light blocking portion, and the invisible area is an area invisible during virtual image observation by the observer due to the second light blocking portion.
