摘要： Provided is laminated glass using an intermediate film having a wedge angle profile that is capable of reducing a double image on a HUD resulting from the influence of the curvature in the longitudinal direction of the window as well as the curvature in the horizontal direction of the window. Laminated glass for a vehicle front window includes a curved first glass plate having a trapezoidal or rectangular shape, a second glass plate having the same shape as the first glass plate, and an intermediate film disposed between the first glass plate and the second glass plate. The laminated glass is provided with an imaging section of an image projected from an imaging device incorporated in a dash board on a driver's seat side in an indoor side surface of the laminated glass, in a state in which the laminated glass is incorporated in a vehicle body. The intermediate film is provided with a wedge angle profile with a thickness continuously changing in all 360° directions in observation from the inside of the vehicle when an upper longitudinal direction from the imaging section is set to 0°, and has a thickness of the intermediate film based on the wedge angle profile continuously decreasing from an upper side to a lower side and continuously decreasing in the horizontal direction from the driver's seat side to the passenger seat side.
