ることが有効であると開示されている。Incidentally, a half mirror is often provided on a part of a windshield of an automobile or the like using laminated glass. Then, driving information light is emitted from the information light projecting means arranged on the dashboard in the vehicle toward the half mirror, and this light is reflected toward the driver, so that driving information such as the traveling speed is transmitted to the driver. It can be visually recognized. A system having such a configuration is called a head-up display, and allows a driver to visually recognize driving information without changing his line of sight toward the outside of the vehicle. By the way, in such a head-up display, the driving information light travels to the driver through another optical path due to the reflection on the outside glass plate as well as the reflection on the half mirror.
As a result, the driver visually recognizes the double image of the driving information. Japanese Patent Application Laid-Open No. 2-279439 and U.S. Pat. No. 5,130,174 disclose that it is effective to use a film for laminated glass having a wedge-shaped cross section as a means for preventing the double image. ing.
