Tempered glass, a preparation method therefor and the use thereof. The difference between the average density of an exposed region and the average density of a non-exposed region of the tempered glass is controlled within a certain range, so as to achieve a balance between the density of the exposed region and the density of the non-exposed region, thereby reducing the amount of deformation of the tempered glass during thermal treatment while increasing the light transmittance difference between the exposed region and the non-exposed region, and thus reducing the degree of warpage of the tempered glass.
