1. A glass article comprising:
a first surface, which is flat;
a second surface opposed to the first surface;
a side surface connecting the first surface to the second surface;
a first surface compressive region extending from the first surface to a first depth;
a second surface compressive region extending from the second surface to a second depth; and
a side compressive region extending from the side surface to a third depth,
wherein the first surface and the side surface are non-tin surfaces,
wherein the second surface is a tin surface, and
wherein a maximum compressive stress of the second surface compressive region is greater than a maximum compressive stress of the first surface compressive region,
wherein a total compressive energy of the first surface compressive region and the side compressive region is equal to a total compressive energy of the second surface compressive region.
