1. A chemically strengthened gradient glass, comprising:
a glass body, a haze of at least a part of an outer surface of the glass body being greater than 0, the haze gradually changing in a predetermined direction, and a light transmittance at any position of the glass body being greater than 85%,
wherein in the predetermined direction, a difference between a maximum value of the haze and a minimum value of the haze is 20% to 80%, and wherein the glass body has a surface compressive stress (CS) of greater than or equal to 680 MPa and less than or equal to 850 MPa and a depth of layer (DOL) of greater than or equal to 8 μm and less than or equal to 10 μm.
