1. A glass plate structure comprising:
a glass plate comprising a first major surface and a second major surface;
an antireflection film provided on or above the first major surface; and
a print portion provided on the second major surface,
wherein the first major surface comprises: a curved surface region that is a region of an end portion of the glass plate, is curved convexly, and has a radius of curvature r that is 50% or more of a thickness t of the glass plate; and a flat surface region that is connected to the curved surface region,
the antireflection film is a laminate in which a high refractive index layer and a low refractive index layer are laminated alternately,
the number of layers of the antireflection film is 12 or smaller,
a total thickness of the antireflection film in the flat surface region is 400 nm or smaller,
a thickness of an outermost layer of the antireflection film in the flat surface region is 90 nm or larger,
a thickness of the outermost layer of the antireflection film in the curved surface region is 80 nm or larger, and
a Y value in the Yxy color system of the curved surface region on which the antireflection film is provided is 2.0 or less.
