Title:
GLASS SHEET
Document Type and Number:
WIPO Patent Application WO/2018/021279
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a glass sheet which exhibits high strength and uniform and high light diffusion properties, and is suitable for obtaining large, thin sheets with narrow bezels. The present invention pertains to a glass sheet having a first main surface and a second main surface facing the first main surface, the glass sheet being characterized in that: the haze, that is, the average total light transmittance at a wavelength of 400-700 nm for incident light entering from a direction normal to the first main surface and passing through the second main surface, is within a specific range; the glass sheet is made of a phase-separated glass in which the content of divalent iron, as converted into Fe2O3 content, is within a specific range; and a value, obtained by dividing the content (mass ppm) of divalent iron, as converted into Fe2O3 content, by the percentage value of the average total light transmittance at a wavelength of 400-700 nm for the incident light passing through the phase-separated glass, is within a specific range.
