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 machining apparatus for a curved plate includes a holder that holds a main surface of a curved plate having curved surfaces on both main surfaces; a machining device that machines an outer circumference of the curved plate held by the holder; a movable frame that retains the machining device; a driver that moves the movable frame to move a machining point of the curved plate held by the holder; a controller that controls the driver; and a guide that guides the movable frame along the outer circumference of the curved plate held by the holder.
