    Abstract: A head-up display of the present disclosure projects a display image on a transparent reflecting member. The head-up display includes: a display device that displays the display image; and a projection optical system that projects the display image displayed on the display device. On an assumption that light reaching a center of a viewpoint region of the observer and corresponding to a center of the virtual image is reference light, the projection optical system includes a prism element that has an incident surface, a reflection surface, and an emitting surface different from the incident surface sequentially in an optical path from the display device. The emitting surface is inclined to the reference light. An inclination amount θ2 of the reference light emitted from the emitting surface with respect to the emitting surface lies in a range of 15°

    Abstract: A head-up display displays an image as a virtual image to an observer and includes: a display device to display the image; and a projection optical system to enlarge and project the image. The projection optical system includes first and second optical elements arranged in this order in an optical path from the image. The first optical element has a diverging action stronger in a horizontal direction than in a vertical direction. The second optical element has a converging action stronger in the horizontal direction than in the vertical direction. A combined power of the first and second optical elements is larger in the vertical direction than in the horizontal direction. The virtual image is inclined by 45 degrees or more with respect a line of sight of the observer to have a lower end close to the observer and an upper end far from the observer.

    Abstract: A head-up display is mounted to a vehicle having a windshield, and includes a display element configured to display an image, a first optical system configured to reflect the image displayed by the display element and project the image onto the windshield; and a second optical system configured to reflect the image displayed by the display element and project the image onto the windshield. The image projected with the first optical system is projected onto the windshield at a position below a position of the image projected with the second optical system.

    Abstract: A head-up display according to the present disclosure is mounted to a vehicle having a windshield and allows an observer to visually recognize a virtual image. The head-up display includes a display element configured to display an image, a reflection optical system configured to reflect the image displayed by the display element and project the image onto the windshield, and a refraction optical system disposed between the reflection optical system and the windshield and having optical power. The reflection optical system reflects the image toward the refraction optical system. The head-up display is configured such that a position where a center optical path of the image emitted from the display element is incident on the refraction optical system is located at a side of the windshield of the vehicle relative to a center axis of the refraction optical system.
