Membranes produced by other methods are difficult to simultaneously achieve low refractive index and sufficient strength. The present invention provides an anti-reflecting membrane which is formed at least on one side of a plate transmitting visible light, is composed of fine inorganic oxide particles and a binder, contains a number of pores inside, and has an arithmetic average surface roughness (Ra) below 6 nm. The present invention also provides preferred embodiments of the display apparatuses provided with the membrane.

  • Patent number: 8053987
    Abstract: It is an object of the present invention to provide a PDP and an FED with excellent visibility and a high level of reliability that each have an antireflective function by which reflection of external light can be reduced. A plurality of adjacent pyramidal-shaped projections and an antireflective layer equipped with a covering film that covers the projections are provided. The reflection of light is prevented by the index of refraction of incident light from external being changed by a pyramid, which is a physical shape, projecting out toward an external side (atmosphere side) of a substrate that is to be used as a display screen as well as by the covering film used to cover the projections being formed of a material that has a higher index of refraction than the index of refraction of the pyramidal projection.
