Abstract: An anti-reflective laminate includes: a substrate; and an anti-reflective layer having a four-layer structure including a first refractive index layer, a second refractive index layer, a third refractive index layer, and a fourth refractive index layer. The first refractive index layer has a refractive index of 1.25 to 1.50, the second refractive index layer has a refractive index of 1.50 to 2.40, the third refractive index layer has a refractive index of 2.25 to 2.45, and the fourth refractive index layer has a refractive index of 1.25 to 1.50. The first refractive index layer has a thickness of 40 to 105 nm, the second refractive index layer has a thickness of 60 to 90 nm, the third refractive index layer has a thickness of 80 to 110 nm, and the fourth refractive index layer has a thickness of 70 to 100 nm.
