Abstract

Provided is laminated glass that can suppress ghosting. This laminated glass: has one end and another end that is on the opposite side from the one end and is thicker than the one end; and comprises afirst laminated glass member, a second laminated glass member, and an intermediate film that is arranged between the first laminated glass member and the second laminated glass member. The intermediate film has a wedge angle of 0.10-2.0 mrad, and the wedge angle of the laminated glass is greater than the wedge angle of the intermediate film.

Description

technical field [0001] The present invention relates to a laminated glass using an interlayer film. Background technique [0002] In general, even when laminated glass is damaged by external impact, the amount of scattered glass fragments is small, and it is excellent in safety. Therefore, the laminated glass is widely used in automobiles, rail vehicles, airplanes, ships, buildings, and the like. The laminated glass is produced by interposing an interlayer film for laminated glass between a pair of glass plates. [0003] In addition, a head-up display (HUD, Head-up Display) is known as the laminated glass used for automobiles. In the HUD, the driving data of the car, such as measurement information such as speed, can be displayed on the windshield of the car, and the driver can recognize the display reflected in front of the windshield. [0004] In the above-mentioned HUD, there is a problem that measurement information and the like appear as ghost images. [0005] To su...
