The present invention provides an antireflection substance such as an antireflection film having a low moisture-permeable characteristic, high quality and high reliability, and also provides a display apparatus comprising this antireflection substance. The antireflection substance according to the present invention includes an antireflection film formed on a transparent substrate, the antireflection film being composed of a multiple layer in which a first layer serving as an adhesion-improving layer, a second layer serving as a barrier layer against moisture, a third layer, a fourth layer and a fifth layer are laminated in this order, and in which the second layer and the fourth layer are each set to have a refractive index higher than that of the third layer and the fifth layer. The display apparatus according to the present invention comprises this antireflection substance on its display surface.
