Transparent head-up display device

The invention relates to the technical field of head-up displays, and provides a transparent head-up display device which comprises a substrate, a light source assembly, a first light guide assembly and a second light guide assembly, the light source assembly is arranged on the substrate, the first light guide assembly is correspondingly arranged above the light source assembly, and the second light guide assembly is correspondingly arranged above the light source assembly. The first light guide assembly is used for guiding at least part of non-vertical light rays emitted by the light source assembly into vertical emergent light rays, the second light guide assembly is coupled with the first light guide assembly, and the second light guide assembly is used for guiding the vertical emergent light rays to the visible range of a driver. By means of the arrangement, the transparent head-up display device can effectively improve the display quality and improve the driving safety coefficient. 本发明涉及抬头显示器技术领域，本发明提供一种
