Beschreibung
Zusammenfassung:	The present invention is directed to an antireflection film having a multilayer structure in which an antireflection multi-layer film including at least two thin films is formed on a substrate, wherein at least one of the thin films contains a coloring agent. The antireflection multi-layer film absorbs light of an entire range of wavelength of 400-700 nm, and the reflectance of the antireflection multi-layer film with regard to the wavelength, light of which this antireflection multi-layer film can absorb, is smaller than the reflectance of the substrate. The antireflection film can be applied to a cathode ray tube or a light-transmitting display substrate of a display apparatus such as a liquid crystal display apparatus for the purpose of effectively avoiding reflection of external light.
