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-guiding prism includes a first optical surface which is a surface of incidence on which image light from a display element is incident, and a second optical surface, a third optical surface, a fourth optical surface, and a fifth optical surface which are at least four optical surfaces disposed to surround an optical path of the image light that is incidence from the first optical surface. A sixth optical surface reflects the image light that is guided in a prism surrounded by that at least four side surfaces, which are the second optical surface, the third optical surface, the fourth optical surface, and the fifth optical surface. The fourth optical surface and the fifth optical surface are inclined at a surface perpendicular to a surface include an incident-light axis of the image light, made by the incident-light axis and a reflected-light axis of the sixth optical surface. Moreover, the fourth optical surface and the fifth optical surface are inclined at a surface perpendicular to the incident-light axis. Furthermore, the sixth optical surface which is a reflecting surface has a rectangular shape.

Abstract: The head-mounted display device includes a display element, a light guide prism that, in a state of use, guides a regular image light beam from the display element to an exit surface in front of the user's eye, and a support that secures the display element and the light guide prism with respect to the user's head. On at least one side along the optical axis of the regular image light beam, the light guide prism includes at least one first-type inclined surface at a position outside of the region through which the regular image light beam from the display element passes, and the first-type inclined surface is formed to be inclined so as to cause light incident on the first-type inclined surface from a direction along the optical axis of the regular image light beam to be reflected and emitted to the outside of the user's eyeball.

Abstract: An eyeglass-type display apparatus includes an eyeglass-front to be placed in front of the eyes of a user, left and right temples connected to the eyeglass-front and worn on the head of the user, a connector that adjusts the inclination of the eyeglass-front by rotating the eyeglass-front relative to the left and right temples, and an image display unit that is fixed to the eyeglass-front and projects image light onto an eyeball of the user. An axis of rotation of the connector is positioned on the eyeglass-front side of the center of the user's eyeball as viewed from the side.

Abstract: An eyepiece optical member has an easy-to-clean interior, and a head-mounted display device is provided with the eyepiece optical member. The eyepiece optical member includes a housing with a built-in display element, a light guide prism in which image light from the display element enters through an entrance surface and is guided to exit from an exit surface towards an eyeball of an observer so as to be observed as a magnified virtual image, and a protective member formed separately from the housing and covering a portion of the light guide prism. The housing includes two opposing plate-like portions, the light guide prism is fixed to the protective member as an assembled member, and the assembled member is sandwiched between the two opposing plate-like portions. The head-mounted display device includes a support member for fixation to a wearer's head and includes the eyepiece optical member attached to the support member.
