摘要： To provide a display device that can suppress generation of a double image. Display device (100) includes plate-shape windshield (100b) having translucency and a projection unit that projects light expressing an image onto windshield (100b) such that the light is reflected toward a user by windshield (100b). The projection unit changes a display distance between an eye of the user and a position of an image visually recognized as a virtual image by the user through windshield (100b) by the light projection. Windshield (100b) is formed such that a wedge angle that is of an angle formed between a front side and a back side at a region located at any level of windshield (100b) is continuously decreased with increasing level.

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).

摘要： The present disclosure provides a head-up display that can prevent generation of stray light from the edge surface by a method other than black coating. The head-up display (100) is for displaying an image as a virtual image (I) to an observer (D) and includes a projection optical system (140) for enlarging and projecting the image. The projection optical system (140) includes a lens element (123) and a reflecting mirror (125). A light beam reaching a center of a viewpoint region (300) of the observer (D) and corresponding to a center of the virtual image (I) is defined as a reference light beam (Lc). The lens element (123) is disposed to be inclined with respect to the reference light beam (Lc). The lens element (123) includes an entrance surface on which light of the image is incident, an exit surface from which light of the image emerges, a first edge portion (123a), and a second edge portion (123b). The second edge portion (123b) is inclined so that, when light emitted from the image travels through the entrance surface, the second edge portion (123b), and the exit surface in this order, light emerging from the exit surface reaches below a central portion of the reflecting mirror (125).

摘要： An object is to provide a head-up display capable of preventing an overlap of a virtual image at a far focus position with a road surface. The head-up display includes an imaging position changer (150) that includes a display device (110) to display an image and a projection optical system (140) for enlarging and projecting the image and is configured to change a position of a virtual image (I 2 ) between a far visual position (P2) far from an observer (d) and a near visual position (PI) close to the observer (d). The imaging position changer (150) is configured to incline the virtual image (I 2 ) at the far visual position (P2) by a second inclination angle with respect to a perpendicular plane to a reference light beam (Lc) reaching a center of a viewpoint region (300) in which a viewpoint of the observer (D) is located, to move an upper end (I 2-u ) thereof in a forward direction of the moving object (200), and incline the virtual image (I 1 ) at the near visual position (PI) by a first inclination angle smaller than the second inclination angle with respect to the perpendicular plane to the reference light beam (Lc), to move the upper end (I 1-u ) in the forward direction of the moving object (200).
