<p>An optical component comprising a plastic substrate and an antireflective film disposed on the substrate, wherein the antireflective film comprises a multilayered film of six or more layers including high refractive index layers and low refractive index layers alternately laminated over each other, and a first layer of the antireflective film which is closest to the substrate constitutes one of the high refractive index layers, and when ? represents a wavelength of a light incident on the antireflective film, then the ? satisfies 480nm = ? = 530nm, an optical thickness (D1) of the first layer satisfies 0.02? = D1 = 0.04?, an optical thickness (Dm) of a fifth layer as counted from an outermost layer of the antireflective film satisfies 0.19? = Dm = 0.75?, a physical thickness (dt) of the entire antireflective film satisfies 350nm = dt = 480nm, and a sum (da) of physical thicknesses of the low refractive index layers satisfies 0.65dt = da = 0.80dt.</p> |
