Abstract

A laminated glass includes a first glass plate, a second glass plate, and an interlayer disposed between the first glass plate and the second glass plate to bond the first glass plate and the second glass plate; the laminated glass partly having a first area configured to be used by a head-up display; the first glass plate having a 4th surface disposed on an opposite side of the interlayer, and a 3rd surface facing the interlayer; the second glass plate having a 2nd surface facing the interlayer and a 1st surface disposed on an opposite side of the interlayer; the first area having a P-polarized light reflective layer disposed on the 4th surface and a light-absorbing layer disposed at a position closer to the 1st surface than the P-polarized light reflective layer; the laminated glass being configured such that the formula of A≥85% is satisfied wherein the total of a visible light transmittance of the P-polarized light reflective layer and a visible light transmittance of the light-absorbing layer is Tv %, the total of a visible light reflectance of the P-polarized light reflective layer and a visible light reflectance of the light absorbing layer is Rv %, and an absorption A is equal to '100−Tv−Rv' (%); and the laminated glass being configured such that the formula of Rvp≥5% is satisfied wherein the total of a P-polarized light reflectance of the P-polarized light reflective layer and a P-polarized light reflectance of the light-absorbing layer is Rvp % when P-polarized light is incident on the surface of the laminated glass facing the P-polarized light reflective layer at an incident angle of 57 deg.
