Abstract: The present invention relates to a plate with a printing layer containing a plate having a first main surface, a second main surface and an edge face, and a printing layer provided on a periphery of the first main surface, in which the plate has an outer circumferential part corresponding to an outer circumferential part of the printing layer and an inner circumferential part corresponding to an inner circumferential part of the printing layer, in which the outer circumferential part of the plate has, in at least a part of the whole circumference, an outer circumferential region, and the inner circumferential part of the plate contains an inner circumferential region corresponding to the outer circumferential region, and in which the outer circumferential region has a surface roughness R2 and the inner circumferential region has a surface roughness R1, and R2>R1 is satisfied.

Abstract: A cover glass includes: a glass substrate having a convex and concave shape formed on at least one of surfaces thereof by an antiglare treatment; and an antireflection film disposed on the surface of the glass substrate, the surface having the convex and concave shape. In the cover glass, a difference Δa* in a* value between any two points within a surface of the cover glass on the side where the antireflection film is present and a difference Δb* in b* value between any two points within the surface of the cover glass on the side where the antireflection film is present satisfy the following expression: √{(Δa*)2+(Δb*)2}≤4.
