Laminated glass
A laminated glass includes a first glass plate; a second glass plate; an intermediate film located between the first glass plate and the second glass plate, and configured to be bonded to the first glass plate and the second glass plate; and at least one high reflection surface between a surface of the first glass plate on an outer side of the laminated glass and a surface of the second glass plate on an outer side of the laminated glass. The surfaces of the first glass plate and the second glass plate are high reflection surfaces. Each of the high reflection surfaces has optical reflectance of 1% or more with respect to an incident angle of a visible light from a light source. A portion arranged between adjacent high reflection surfaces of the high reflection surfaces has a wedge angle.
1. A laminated glass comprising:
a first glass plate;
a second glass plate;
an intermediate film located between the first glass plate and the second glass plate, and configured to be bonded to the first glass plate and the second glass plate; and
at least one high reflection surface between a surface of the first glass plate on an outer side of the laminated glass and
