A laminated glazing for use as a combiner in a head up display is described. The laminated glazing comprises first and second glazing panes with at least one adhesive ply and an infrared reflecting film therebetween. Light incident upon the first glazing pane at an angle of incidence of 60o is reflected off the laminated glazing to produce first, second and third reflections, the third reflectionbeing from light reflected from the infrared reflecting film. The laminated glazing further comprises light intensity reducing means between the first and second glazing panes for reducing the intensity of the third reflection. In an aspect, upon directing a beam of electromagnetic radiation having an intensity I o at 770nm toward the first pane of glazing material at an angle of incidence of 60 degrees, the intensity of the third reflection at a wavelength of 770nm is less than or equal to 0.185*Io. 描述了用作平视显示器中的组合器的夹层窗玻璃。该夹层窗玻璃包含第一和第二窗玻璃板，在它们之间具有至少一个粘合剂层和红外线反射膜。以60°入射角入射到第一窗玻璃板上的光被反射离开夹层窗玻璃而产生第一、第二和第三反射，该第三反射来自从红外线反射
