ABSTRACT:
A windshield having a windshield body and a specific area, which is arranged at a part in a longitudinal direction of the windshield body and is formed into a curved surface having a curvature different from the curvature of the windshield body, is provided. The specific area is formed into a round shape in a plan view. The specific area has a projection area, on which a display light of an image displayed on a display device mounted in a vehicle is projected and the projection area is formed into a curved surface for displaying the projected image in a desired shape and is arranged outside of a surface of the windshield body, and a connection area, which is arranged around the projection area and is formed into a curved surface for continuing to the projection area and the windshield body. By using the windshield, the projection area can be formed into the windshield without an extra deformation.
