HEAD-UP DISPLAY GLASS AND HEAD-UP DISPLAY SYSTEM

Provided are a head-up display glass (100) and a head-up display system (1000). The head-up display glass (100) comprises laminated glass and a reflective film layer (40); the laminated glass comprises an outer glass plate (10), a polymer intermediate layer (30), and an inner glass plate (20); the reflective film layer (40) comprises an inner blocking layer (41), an improvement layer (42), and at least one laminated structure (43) which are stacked. The inner blocking layer (41) can block the damage of alkali metal ions on the surface of the glass to the improvement layer (42) during a heat treatment process and block the oxidation of the improvement layer (42) by the diffusion of oxygen, and the improvement layer (42) can further improve the reflectivity of the reflective film layer (40) for P-polarized light while maintaining the reflective film layer (40) having low reflectivity for visible light, so that when a driver in a vehicle visually observes a reflective image of the head-up display glass (100), on
