Abstract: A glass plate structure includes: a glass plate having first and second major surfaces; an antireflection film; and a print portion. The first major surface includes: 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.

Abstract: A manufacturing method of a glass article having an organic film includes irradiating a first main surface of a glass plate having the first main surface and a second main surface, opposite each other, with a laser light of a first laser, to form an in-plane void region, in which voids are arrayed, on the first main surface, and internal void arrays, including voids arrayed from the in-plane void region to the second main surface, in the glass plate;
depositing the organic film on the first main surface or the second main surface of the glass plate; and irradiating and scanning the first main surface or the second main surface, on which the organic film was deposited, with a laser light of a second laser, along the in-plane void region, to separate the glass article from the glass plate along the in-plane void region.

Abstract: To produce a glass plate with resin frame in a short time at a low cost, and to reduce scars on the glass and the resin frame. A method for producing a glass plate with resin frame, which comprises forming a resin frame on a peripheral portion of a glass plate by injection molding, and removing a flash formed at an inner peripheral edge of the resin frame by irradiation with laser beam.

Abstract: A glass plate processing method for dividing a glass plate by a separation line that divides a main surface of the glass plate into two regions, includes: moving an irradiation point of a first laser beam along the separation line, and forming a crack extending from the separation line diagonally with respect to the main surface, in a cross-section orthogonal to the separation line; after the crack is formed, moving an irradiation point of a second laser beam along the separation line, and forming a modified portion, in the cross-section, on a virtual line extending in a direction perpendicular to the main surface, from a tip of the crack towards a center of a thickness of the glass plate; and after the modified portion is formed, applying stress to the glass plate and forming a new crack spanning from the tip of the crack to the modified portion.
