Patent number: 10336163Abstract: A windshield according to the present invention is a windshield to which an information acquisition device that emits and/or receives light to acquire information from an outside of a vehicle can be attached, and that includes a glass sheet, and a mask layer that is formed on the glass sheet and blocks a visual field from the outside of the vehicle, and at least one opening is formed in the mask layer. The glass sheet and the mask layer have different heat shrinkage percentages and are molded together by being heated. The information acquisition device is configured to be capable of using the information while reducing an influence of distortion that occurs in a predetermined range from an inner peripheral edge of the opening toward a center of the opening due to the molding.Type: GrantFiled: March 16, 2015Date of Patent: July 2, 2019Assignee: NIPPON SHEET GLASS COMPANY, LIMITEDInventors: Takumitsu Sakamoto, Satoshi Kanki, Hideaki Oshima, Hisashi Ogawa
