RIGID SUBSTRATE, TOUCH PANEL, AND PROCESSING METHOD OF RIGID SUBSTRATE

摘要

A rigid substrate, a touch panel including the rigid substrate, and a processing method of the rigid substrate are provided. The rigid substrate includes an ion strengthened surface layer completely covering the entire outer surface thereof. The rigid substrate has an etched wall, wherein an average depth of the ion strengthened surface layer on the etched wall is substantially equivalent to an average depth of the ion strengthened surface layer outside of the etched wall.
