The invention relates to a dielectric film, a windshield window, a display device and traffic equipment. The dielectric film comprises at least one first dielectric layer; the second dielectric layers and the first dielectric layers are alternately arranged, and the refractive index of the first dielectric layers is larger than that of the second dielectric layers; the dielectric film is configured to transmit at least part of visible light and reflect at least part of infrared light. The dielectric film provided by the invention has a relatively high visible light transmission characteristic and a relatively high infrared light reflection characteristic, and can reduce the infrared light entering the traffic equipment while ensuring the driving safety so as to reduce the temperature in the traffic equipment.

    本申请涉及一种介质膜、挡风窗、显示装置及交通设备。介质膜包括:至少一层第一介质层;至少一层第二介质层,第二介质层与第一介质层交替设置,第一介质层的折射率大于第二介质层的折射率;介质膜配置为透射至少部分可见光,并反射至少部分红外光。本申请的介质膜具有较高的可见光透过特性,且具有较高的红外光反射特性,在保证驾驶安全的同时,能够减少入射到交通设备内的红外光,以降低交通设备内的温度。
