    • An anti-reflection optical member has a laminated structure including: a transparent substrate having a first refractive index greater than that of a predetermined medium; a metal-microparticle-containing layer containing metal microparticles; and a dielectric layer having a second refractive index greater than that of the predetermined medium, in this order. At least 60% of the metal microparticles are flat particles with a diameter-to-thickness ratio of 3 or more. Principal planes of the flat metal particles are surface-oriented in the range from 0° to 30° relative to the surface of the metal-microparticle-containing layer. In the metal-microparticle-containing layer, the metal microparticles are disposed without forming a conductive path. The dielectric layer has such a thickness that light reflected at the surface of the dielectric layer of incident light entering the laminated structure from the surface is interfered and canceled by light reflected at the interface between the dielectric layer and the metal-microparticle-containing layer.
    • 防反射光学构件具有层压结构,包括:具有比预定介质的折射率大的第一折射率的透明基板; 含有金属微粒的金属微粒层; 以及具有比预定介质的第二折射率大的第二折射率的介电层。 至少60%的金属微粒是直径 - 厚度比为3或更大的平坦颗粒。 平面金属粒子的主面相对于金属 - 微粒子层的表面在0°〜30°的范围内进行表面取向。 在含金属 - 微粒子层中,金属微粒被设置成不形成导电路径。 电介质层的厚度使得从表面进入层叠结构的入射光的电介质层的表面反射的光被介电层和含金属 - 微粒层之间的界面反射的光所干扰和抵消。
