发明名称 ANTI-REFLECTION LAMINATE
摘要 To provide an antireflection stack, whereby a reflected color is moderate, and a multicolorization is suppressed. The antireflection stack 1 comprises a substrate 2 and an antireflection layer 3 stacked on the substrate 2. The antireflection layer 3 has a four-layer structure and comprises, sequentially from the substrate side, a first layer 31, a second layer 32, a third layer 33 and a fourth layer 34. Further, the first layer 31 has a refractive index of from 1.6 to 1.9, the second layer 32 has a refractive index of from 2.2 to 2.5, the third layer 33 has a refractive index of from 2.0 to 2.3, the fourth layer 34 has a refractive index of from 1.2 to 1.5, and the refractive index of the second layer 32 is larger than that of the third layer 33.
