  "textContent": "Head-up display glass includes laminated glass (10). The laminated glass (10) has a first surface (10-1) and a second surface (10-2) opposite to the first surface (10-1). The second surface (10-2) includes a display region (31) and a non-display region (32). A first nano-coating (20-1) is disposed in the display region (31). The first nano-coating (20-1) includes at least one first high-refractive-index layer (21-1) and at least one first low-refractive-index layer (22-1) that are alternately stacked from the second surface (10-2) outwards. The at least one first high-refractive-index layer (21-1) each has a refractive index ranging from 1.9 to 2.7. The at least one first low-refractive-index layer (22-1) each has a refractive index ranging from 1.3 to 1.8. The display region (31) has a reflectivity greater than or equal to 10% for P-polarized light incident at an angle ranging from 55° to 75°. For visible light incident at an angle ranging from 0° to 10°, a reflectivity of the non-display region (32) is less than a reflectivity of the display region (31). For the head-up display glass, not only the cost is low, but also an image of head-up display is sharp and a visual interference of the glass is small, thereby ensuring driving safety and driving comfort of during driving. A head-up display system is further provided in the present disclosure.",
