Abstract
A high definition display apparatus having a wavelength selective absorption effect and an anti-static and anti-reflection effect is provided by thin films having a low resistance and a high refractive index. The high definition display apparatus has an anti-static and anti-reflection film composed of laminated oxide or metallic thin films, wherein at least three layers of oxide or metallic films having different reflectance from each other are laminated onto the front surf ace of the display apparatus, and the laminated films are composed such that an absorbing film containing coloring material is arranged under a high reflectance film as seen from the outer surface of the laminated films.
