Claim 0:
1. An antiglare transparent substrate comprising a transparent substrate which comprises a chemically strengthened glass and has a first main surface and a second main surface,
wherein the first main surface comprises:
a first smooth region having an arithmetic average roughness Ra of 0.05 nm or more and 2 nm or less; and
a first rough region having an arithmetic average roughness Ra larger than the arithmetic average roughness Ra of the first smooth region, and
wherein the second main surface comprises, in at least a part of a region facing the first smooth region, a second smooth region having an arithmetic average roughness Ra of 0.05 nm or more and 2 nm or less, and
wherein a surface compressive stress CS of the first smooth region is larger than a surface compressive stress CS of the first rough region.
