Title:
GLASS STRUCTURE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2022/118521
Kind Code:
A1
Abstract:
The present invention provides a glass structure with which perspective distortion near the boundary between a light-shielding processed section and a translucent section can be minimized, an electrothermal film and a busbar can be formed easily and inexpensively, and there is a high degree of freedom in designing the wiring from the busbar. This glass structure (1) has: a light-shielding processed glass plate (10) having an optical device attachment area (OP), a translucent section (TP) which is positioned within the optical device attachment area (OP) and through which passes light entering from the outside on an optical device and/or light exiting the optical device, and a light-shielding processed section (BP) surrounding at least part of the translucent section (TP); and a translucent plate-form member (31) that is thinner than the light-shielding processed glass plate (10) and that is attached so as to cover part of the translucent section (TP) and the light-shielding processed section (BP) on the surface of the light-shielding processed glass plate (10) where the optical device is attached. An electrothermal film (32) and a pair of busbars (41, 42) for supplying electricity to the electrothermal film (32) are formed on the translucent plate-form member (31).
