(JA) 結晶化ガラス基板
Abstract
(EN)
A crystallized glass substrate having a compressive stress layer formed on the surface thereof, wherein the stress depth DOLzero is 45 to 200 μm when the compressive stress of the compressive stress layer is 0 MPa, the compressive stress CS of the outermost surface of the compressive stress layer is 400 to 1400 MPa, and the central stress CT as measured by a curve analysis is 55 to 300 MPa.
