US 11,192,815 B2 · Method for manufacturing bent substrate and bent substrate

Abstract

A method for manufacturing a bent substrate, which forms a bent part in at least a part of a substrate, in which the substrate includes a second region and a first region, the method for manufacturing including: supporting the first region of the substrate on a substrate support surface of a support member including a mold surface having a same curved surface shape as that of the bent part and the substrate support surface that supports the first region, in a state of facing the second region of the substrate to the mold surface; heating the second region of the substrate to soften the second region of the substrate by the heating; placing the second region along the mold surface of the support member by an own weight of the second region; and transferring the curved surface shape of the mold surface to the second region by an external force.

Dependent claims

A bent substrate having a bent part in at least a part thereof, wherein

the bent substrate has a one main surface and the other main surface opposite to the one main surface, and
a surface roughness Ra1 of the bent part on the one main surface of the bent substrate is larger than a surface roughness Ra2 of a region other than the bent part on the one main surface,
wherein the surface roughness Ra1 of the bent part on the one main surface is 1 nm or more and 5,000 nm or less in terms of an arithmetic average roughness,
wherein a surface roughness Ra3 of the bent part on the other main surface is larger than a surface roughness Ra4 of a region other than the bent part on the other main surface, and
wherein the bent substrate comprises a glass.
