Title:
LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2023/190438
Kind Code:
A1
Abstract:
Provided is laminated glass which is to be used in a head-up display, which comprises a first glass plate, a second glass plate, and an interlayer film that is positioned between the first glass plate and the second glass plate and that adheres the first glass plate and the second glass plate, and in part of which is defined an expected projection region that allows incidence of p-polarized light from the first glass plate side. A p-polarized light reflection film is provided in the expected projection region. The residual stress Δu [MPa] in the expected projection region satisfies prescribed expressions in which P-polarized light reflectivity Rp and s-polarized light transmissivity Ts of the laminated glass and the combined thickness t of the first and second glass plates are variables. Thus, sub-images are suppressed in the head-up display, and viewability is improved.
