Abstract: A light guide prism that is used by being placed in front of a user's eye and guides image light from a display device to the user's eye for observation as a virtual image includes a first light-guiding portion, a second light-guiding portion, and a level difference positioned between the first light-guiding portion and the second light-guiding portion. In a state of use in front of the user's eye, the second light-guiding portion is positioned at a front side of the user's eye, the first and second light-guiding portions each have uniform thickness, a vertical thickness of the second light-guiding portion being less than a vertical thickness of the first light-guiding portion with the level difference as a boundary, and the level difference extends at an inclination with respect to an exit optical axis of the light guide prism so as not to enter the user's field of view.

Abstract: A head-mounted display device is provided, the head-mounted display device including: a display element; a light guide prism that includes an incident surface through which image light from the display element enters and that guides the image light to user's eyes; and a housing that contains the display element and the light guide prism; and support unit that fixes the housing to user's head. The light guide prism is partially covered by and contained in the housing. A portion of side surface of the light guide prism covered by the housing is formed with a first groove, and portion of side surface of the light guide prism exposed outside the housing is formed with a second groove. Depth of the first groove measured from the side surface is greater than that of the second groove.

Abstract: A light guide prism for guiding image light from a display device to an observer's eye and displaying a virtual image of the display device in the observer's field of view includes at least four sides disposed to surround an optical path of image light incident from one end, a reflecting surface configured to reflect the image light guided by the at least four sides, and an emission surface configured to emit the image light reflected at the reflecting surface towards the observer's eye. At least one groove in a V-shape is formed on each of the at least four sides. As a result, a light guide prism that reduces stray light and ghost light occurring due to reflection at inner surfaces and an image display apparatus using this light guide prism can be provided.
