CHEMICALLY STRENGTHENED GLASS PLATE, AND COVER GLASS AND ELECTRONIC DEVICE COMPRISING CHEMICALLY STRENGTHENED GLASS

摘要

The purpose of the present invention is to provide a chemically strengthened glass plate wherein flexure fracture and fracture due to collision with a protruding object are both effectively suppressed and, furthermore, fragmentation upon breakage is suppressed. The present invention pertains to a chemically strengthened glass plate wherein SB/(SA × t) is 5.0 mm^-1 or greater (wherein: SA [MPa•μm] stands for an integrated value of compression stress from the surface of the glass plate to the depth of 10 μm; SB [MPa•μm] stands for an integrated value of compression stress from the depth of 10 μm to DOL that means the depth at which the compression stress reaches zero; and t [mm] stands for the thickness of the plate).
