This application discloses a panoramic glass assembly and a vehicle. The panoramic glass includes a roof and the panoramic glass itself. A gap is formed between the roof and the panoramic glass in the thickness direction of the panoramic glass, and the gap is greater than or equal to 3 mm. The parallax index of the panoramic glass is defined as R, where 0 ≤ R ≤ 1.5. The parallax index of the panoramic glass is equal to the ratio of the visible light transmittance of the panoramic glass to the reflectance of the outer side wall of the panoramic glass facing away from the roof. By using the panoramic glass assembly of this application, a dark chamber space is formed between the panoramic glass and the roof, and the panoramic glass has a one-way invisible visual effect. Thus, pedestrians cannot see the internal structure of the panoramic glass from the outside, improving the overall aesthetics of the vehicle.
