Abstract
To provide an optical member that enables a light guiding plate to be firmly fixed with certainty to a rim portion using an adhesive. An optical member of the present disclosure that guides light that enters from an image forming apparatus such that the light exits the optical member to be headed for an observer, includes a light guiding platethat is formed of a resin plate', a first deflection mechanism, and a second deflection mechanism. Light that enters the light guiding platefrom the image forming apparatus is deflected by the first deflection mechanism, is totally reflected within the light guiding plateto propagate through the light guiding plate, is then deflected by the second deflection mechanism, and exits the light guiding plateto be headed for the observer. The light guiding plateincludes a protrusionthat extends from a portion of a lateral surface of the light guiding plate. Further, the light guiding plateis fixed to an interior lateral faceA of a rim portionusing an adhesivein a state in which a tip of the protrusionis in contact with the interior lateral faceA of the rim portion
