摘要： A head-up display system includes a display that emits a light flux visually recognized by an observer as the virtual image and a light guide body that guides the light flux to the light-transmitting member. The light guide body includes an incident surface on which the light flux from the display is incident and an emission surface from which the light flux is emitted from the light guide body. A light beam at a center of the light flux emitted from the display is incident while being inclined with respect to a normal direction of the incident surface of the light guide body. The light flux incident on the incident surface of the light guide body is changed in a traveling direction in the light guide body, the light flux is replicated into a plurality of light fluxes in a horizontal direction of the virtual image visually recognized by the observer, and then the replicated light fluxes are further replicated in a vertical direction of the virtual image to be emitted from the emission surface so as to expand the visual recognition region. A light beam at a center of the light fluxes emitted from the light guide body is emitted toward the light-transmitting member while being inclined with respect to a normal direction of the emission surface of the light guide body.

摘要： A display apparatus of the present technique includes a display unit configured to project an image onto a light transmissive display member, and forms a virtual image, of the image projected by the display unit, on an opposite side of the display member to a user. The display unit is configured such that a display device for displaying an image and a projection optical system for projecting the image displayed on the display device onto the display member are housed in a housing having an opening through which projection light is emitted. The projection optical system includes, on an optical path from the display device to the opening, a first reflection member disposed on a display device side and a second reflection member disposed on an opening side. The first reflection member has a reflection surface which reflects the image displayed on the display device and has a convex shape, and the second reflection member has a reflection surface which projects the image onto the display member and has a free curved concave shape. Further, a relationship between vertical length Yv of the image displayed on the display device and distance T, on a central optical path, from the user to the virtual image satisfies 0.03

The light guide body includes an incident surface on which the light flux from the display is incident and an emission surface from which the light flux is emitted from the light guide body. The light flux incident on the incident surface of the light guide body is changed in a traveling direction in the light guide body, the light flux is replicated into a plurality of light fluxes in a direction perpendicular to a horizontal direction of the virtual image visually recognized by the observer to be emitted from the emission surface so as to expand a visual recognition region. When a direction indicated by a normal on the visual recognition region side in a normal direction of the light-transmitting member at an intersection of the light-transmitting member and the Z-axis is defined as a direction A, and a direction connecting a center of the visual recognition region of the virtual image and an emission port of the display is defined as a direction B, the direction A and the direction B intersect each other in the XZ plane between the visual recognition region and the light-transmitting member.

摘要： An optical system (3) includes: a projection optical system (5) for projecting an image light ray (L1) which is output from a display element (2) and forms an image; and a light guide (4) for guiding the image light ray (L1) projected by the projection optical system (5) toward a field of view region (7) of a user as a virtual image. The light guide (4) includes: an in-coupling region (41) for guiding the image light ray (L1) to an inside of the light guide (4) and allowing the image light ray (L1) to travel in a first axis (X axis) direction within the light guide (4); and a propagation region (42) for allowing the image light ray (L1) from the in-coupling region (41) to propagate in the direction of the first axis, and allowing part of the image light ray (L1) to travel in a predetermined direction including a directional component of a second axis (Y axis) perpendicular to the first axis. In an optical path of the image light ray (L1) projected by the projection optical system (5), a distance (D1) from the projection optical system (5) to an entrance pupil (P1) of the projection optical system (5) relative to the display element (2) in a plane perpendicular to the first axis is longer than a distance (D10) from the projection optical system (5) to the in-coupling region (41).
