Abstract:
A glass resin laminate includes a sheet glass having a compressive stress layer formed in a main surface thereof and a resin layer provided on the sheet glass. A surface compressive stress in the main surface of the sheet glass is 200 MPa or more. A depth of the compressive stress layer is 3 μm or more. A central tension CT (MPa) and a sheet thickness t (mm) of the sheet glass satisfy the equations CT≤64.1× t−0.703 (4) and CT>−38.7×ln(t)+48.2 (5).
Abstract:
The present invention provides a cover glass for a display, having high durability to slow cracking and strong abraded strength even though a compressive stress is large and a depth of a compressive stress layer is deep. The present invention relates to a cover glass for a display, in which a depth of a compressive stress layer (DOL) is 30 μm or more, a surface compressive stress is 300 MPa or more, a position (HW) at which a compressive stress is half of a value of the surface compressive stress is a position of 8 μm or more from a glass surface, and the depth of the compressive stress layer (DOL) and the position (HW) at which the compressive stress is half of the value of the surface compressive stress satisfy the following formula: 0.05≦HW/DOL≦0.23 (1).
