HEAD-UP DISPLAY GLASS AND HEAD-UP DISPLAY SYSTEM THEREOF

Head-up display glass. The head-up display glass comprises laminated glass (10), wherein the laminated glass (10) comprises a first surface (10-1) and a second surface (10-2), which face away from each other; the second surface (10-2) comprises a display region (31) and a non-display region (32); the display region (31) is provided with a first nano-film (20-1); the first nano-film (20-1) comprises at least one first high-refractive-index layer (21-1) and at least one first low-refractive-index layer (22-1), which are sequentially stacked outward from the second surface (10-2), the refractive index of the first high-refractive-index layer (21-1) being 1.9-2.7, and the refractive index of the first low-refractive-index layer (22-1) being 1.3-1.8; and the reflectivity of the display region (31) for P-polarized light that is incident at 55°-75° is greater than or equal to 10%, and the reflectivity of the non-display region (32) for visible light that is incident at 0°-10° is less than the reflectivity of the dis
