Abstract
A vehicle head-up display device for preventing ghost images, includes a base, a display module and a lid, wherein the lid is translucent material, a lower thickness of the lid is smaller than an upper thickness, the display module is used to project image information on the lid. By the composition of the above elements, the variation in thickness that the upper of the lid is thick and the lower of the lid is thin is used to generate the refraction of the prism, to let the position of ghost images be overlapped with real images, to thereby effectively solve the problem of ghost images.
