[Problem] To provide a laminated glass provided with an intermediate film having a wedge angle profile that can reduce double images in a HUD which are formed as the result of the influence of a longitudinal-direction curvature of a window as well as the influence of a horizontal-direction curvature of the window. [Solution] A laminated glass for vehicle front windows, which is provided with a curved trapezoidal or rectangular first glass plate, a second glass plate having the same shape as that of the first glass plate, and an intermediate film arranged between the first glass plate and the second glass plate, wherein, in a state where the laminated glass is integrated in a vehicle body, an image-formed part of an image projected from an imaging device integrated in a driver-seat-side dashboard is included in an indoor-side surface of the laminated glass, the intermediate film has such a wedge angle profile that the thickness is changed continuously in all directions of 360 degrees when the upper vertical direction from the image-formed part is defined as 0 degree in the observation of the intermediate film from the indoor-side surface, and the thickness of the intermediate film on the basis of the wedge angle profile decreases continuously from the upper edge side toward the lower edge side and also decreases continuously from the driver-seat-side toward the passenger-seat-side in the horizontal direction.

    本发明提供一种夹层玻璃,该夹层玻璃使用如下中间膜,该中间膜具有不仅能够减少由窗的纵向的曲率的影响造成的HUD的重影,而且能够减少由水平方向的曲率的影响造成的HUD的重影的楔角轮廓。一种车辆的前车窗用的夹层玻璃,其具备弯曲的梯形或矩形的第一玻璃板、与所述第一玻璃板形状相同的第二玻璃板、以及配置于所述第一玻璃板与第二玻璃板之间的中间膜,在所述夹层玻璃组装入车体的状态下,所述夹层玻璃的室内侧面包括自组装入驾驶座侧的仪表板的影像装置投射的图像的成像部,在从车内观测时,从所述成像部起将上纵向设为0°时,所述中间膜具备厚度在全部360°的方向上连续地变化的楔角轮廓,基于所述楔角轮廓的中间膜的厚度在从上边侧到下边侧的范围内连续地减小,并且,从驾驶座侧向副驾驶座侧沿水平方向连续地减小。
