Title:
WINDSHIELD
Document Type and Number:
WIPO Patent Application WO/2015/170771
Kind Code:
A1
Abstract:
The present invention is a windshield in which it is possible to install an information obtaining device that obtains information from outside the vehicle by radiating light and/or receiving light. The windshield is provided with a glass plate on which a mask layer is laminated, the mask layer blocking visibility from outside the vehicle and having at least one opening. The glass plate and the mask material forming the mask layer have differing coefficients of thermal expansion, and the glass plate and the mask layer are both heated and thereby shaped. In at least a portion of the peripheral edge of the opening in the mask layer, formed is an opening peripheral edge region in which the proportion of the mask material disposed per unit area is low. The information obtaining device is disposed in the opening on the surface of the glass plate inside the vehicle so as to be able to obtain information through a region further inside than the opening peripheral edge region.
