The present disclosure relates to the technical field of automotive glass, and in particular to laminated glass and vehicles. Currently, electric vehicles are beginning to adopt panoramic windshields (or referred to as panoramic windshields). Compared to conventional windshields, panoramic windshields provide a wide vertical field of view to occupants inside the vehicle by extending the upper edge of the windshield toward the roof to include at least a portion of the roof. Regarding the panoramic front windshield described above, while the occupant's field of view has been expanded, the possibility of a problem where light rays are too strong in certain scenes is considered. To resolve this issue of excessive light rays, one current method is to implement a shadow gradient design corresponding to the upper central side of the glass, for example, by forming a gradient color area on the upper central side of the glass. However, with the advancement of science and technology, the demand for panoramic windshields is steadily increasing. To better satisfy the user's riding experience, it is necessary to further optimize conventional windshields.
