Document Type and Number:
WIPO Patent Application WO/2021/256089
Kind Code:
A1
Abstract:
The present invention provides a glass structure comprising a glass substrate in which a stepped surface formed by the difference in level between a thick sheet portion and a thin sheet portion is not readily visually recognizable. A glass structure (1) is provided with: a glass substrate which has a thick sheet portion (3) and a thin sheet portion (4); and a filler (6) that covers a stepped surface (5) formed by the difference in level between the thick sheet portion (3) and the thin sheet portion (4). The difference in the refractive index between the glass substrate (2) and the filler (6) at a wavelength of 555 nm is 0.008 or less in absolute value, and the difference in the refractive index between the glass substrate (2) and the filler (6) at a wavelength of 507 nm is 0.008 or less in absolute value.
