  • Publication number: 20180339939
    Abstract: A glass article includes a glass plate including a rugged surface configured to diffuse and reflect an external light formed on at least one of main surfaces; and a functional film formed on the rugged surface. A transmission haze of the glass article is 28% or less. On a surface of the functional film opposite to the glass plate, within a region with a visual field area of 60000 ?m2 observed by using a laser microscope, a pore representative diameter is less than 12 ?m. An area ratio of a surface area A (?m2) of the surface of the functional film within the region to the visual field area (A/60000) is 1.02 or more and 1.07 or less.
