Abstract

To provide an image generation unit and a head-up display device.SOLUTION: An image generation unit includes a display panel, a first illumination system, and a second illumination system. The display panel has a first imaging surface and a second imaging surface adjacently arranged and located on a same plane. The first illumination system is used for providing a first light beam, the first light beam is incident on the first imaging surface at a first incident angle, and the first imaging surface converts the first light beam into a first image beam. The second illumination system is used for providing a second light beam, the second light beam is incident on the second imaging surface at a second incident angle, and the second imaging surface converts the second light beam into a second image beam. A propagation path of the first light beam incident on the first imaging surface and a propagation path of the second light beam incident on the second imaging surface do not intersect with each other, and the first image beam and the second image beam leave the display panel at different light exit angles.SELECTED DRAWING: Figure 1
