Abstract
A plasma display panel having a structured black matrix ( ) which is coated with a reflecting layer ( ) on the side turned away from the viewer. Visible light incident from outside is absorbed by the black matrix ( ) and light incident from inside is reflected by the reflecting layer ( ). This enhances the LCP value of the whole plasma screen. A protective layer ( ) such as MgO is deposited on the black matrix and reflecting layer and so formed over the black matrix and said reflecting layer so as to reduce undesired reactions of the black matrix and the reflecting layer with the dielectric layer, such as during high temperature conditions during manufacture.
