Abstract:
1. A plasma display comprising: a pair of substrates; at least a pair of electrodes provided between the pair of substrates; a phosphor layer provided between the pair of electrodes; and an anti-reflection layer provided on an outer side of one substrate of the pair of substrates, wherein the one substrate has a light-transmitting property, wherein the anti-reflection layer comprises a plurality of pyramidal projections, wherein each side of a base of one of the plurality of pyramidal projections is in contact with one side of a base of another pyramidal projection, wherein a space among the plurality of pyramidal projections is filled with a protective layer having a lower refractive index than a refractive index of the plurality of pyramidal projections, and wherein each of the refractive index of the plurality of pyramidal projections and the protective layer increases in direction from an apical portion of each of the plurality of pyramidal projections to the base of each of the plurality of pyramidal projections.
