Claim 0:
1. A glass article including lithium aluminosilicate, comprising:
a first surface;
a second surface opposed to the first surface;
a first compressive region extending from the first surface to a first compression depth;
a second compressive region extending from the second surface to a second compression depth; and
a tensile region disposed between the first compression depth and the second compression depth,
wherein a stress profile of the first compressive region has a first local minimum point at which the stress profile is convex downward and a first local maximum point at which the stress profile is convex upward,
wherein a depth of the first local maximum point is greater than a depth of the first local minimum point,
wherein a stress of the first local maximum point is greater than a compressive stress of the first local minimum point,
wherein a depth of the first local minimum point is 0.24 times to 0.31 times the first compression depth, and
the first compression depth ranges from 105 micrometers to 115 micrometers.
