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.
