Abstract
A laminated glass to be used as a front windshield glass of an automotive vehicle, forming part of a head-up display system for displaying an image of light representing driving information on the windshield glass. The laminated glass comprises inboard-side and outboard-side glass plates of the vehicle. An intermediate film is disposed between and in contact with the inboard-side and outboard-side glass plates. A polarization-direction changing film is disposed between the first and second glass plates and bonded to the outboard-side glass plate with an adhesive containing an ultraviolet ray absorbing agent. The polarization-direction changing film functions to rotate a plane of polarization of light to be incident thereon.
