ABSTRACT:
A laminated glass to be used as a front windshield of an automotive vehicle including a head-up display system. The laminated glass comprises outboard-side and inboard-side glass plates. An intermediate film is interposed between the inboard-side and outboard-side glass plates to bond the glass plates to each other. An optically functioning film such as a polarization-direction changing film is bonded to the outboard-side glass plate. At least one of the inboard-side glass plate, the outboard-side glass plate and the intermediate film is colored in a manner that a color difference between first and second parts of the laminate is not higher than 2.4, in which the first part includes the optically functioning film while the second part is other than the first part.
