Abstract: A door glass for a vehicle includes a laminated glass having a first glass plate, a first adhesive layer, an infrared-reflective film, a second adhesive layer, and a second glass plate laminated in this order. The infrared-reflective film includes a laminate in which 100 or more layers of resin layers having different refractive indices are laminated, and has a thermal shrinkage rate of greater than 0.6% and less than 1.2% in a direction in which the thermal shrinkage rate becomes maximum, and in a direction perpendicular to the maximum direction. In an area where the laminated glass is visible when mounted on the vehicle, the outer periphery of the infrared-reflective film is positioned within a range of up to 10 mm inward from the outer periphery of the laminated glass in front view.

Abstract: A laminated glass has a vehicle exterior side glass plate; a vehicle interior side glass plate; and an intermediate film disposed between the vehicle exterior side glass plate and the vehicle interior side glass plate. The laminated glass includes a display area for reflecting a projected image projected from vehicle interior, to display information. In at least a part of the display area, a film is arranged between the vehicle exterior side glass plate and the vehicle interior side glass plate. The film is a main reflection surface for the projected image. The display area is offset from the edge of the film by 5 mm.
