Abstract
A glass article includes lithium alumino-silicate ('LAS'), a first surface, a second surface opposed to the first surface, a first compressive region extended from the first surface to a first compression depth, a second compressive region extended 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 in the first compressive region comprises a first segment provided between the first surface and a first transition point and a second segment provided between the first transition point and the first compression depth, and wherein a ratio of a stress at the first transition point to a stress at the first surface ranges from 0.22 to 0.47.
