This disclosure relates to the field of head-up display (HUD) technology, and more particularly to an HUD system with a transparent nano film for image display. Specifically, an HUD system including ultra-thin glass is provided in the disclosure. The HUD system includes a projection light source, and laminated glass, and a transparent nano film. The transparent nano film includes at least two metal layers. The projection light source is configured to generate P-polarized light. The laminated glass provided with the transparent nano film has a maximum reflectivity Rmax and a minimum reflectivity Rmin for the P-polarized light that has the incident angle ranging from 45° to 72°, where Rmax/Rmin ranges from 1.0 to 2.0.
