Abstract
An antiglare transparent substrate includes a transparent substrate which includes a chemically strengthened glass and has a first main surface and a second main surface. The first main surface includes: 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. The second main surface includes, 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.
