Abstract: A polarizing plate comprises at least two transparent substrates spaced apart and facing one another, and at least two polarizers provided between an outermost-positioned first transparent substrate and another outermost-positioned second transparent substrate, such that all the polarizers are sealed so as not to be in contact with outer air.

Abstract: A polarizing sheet having a transparent substrate on both surfaces of a polarizing film containing a polarizer, wherein exposed portions of the polarizing film not covered by the transparent substrate are covered with a sealing material.

Abstract: A front panel for a plasma display panel having at least one transparent resin plate and a conductive mesh placed on the transparent resin plate, in which a part of the conductive mesh is exposed on the plate in a sheet form on at least one side of the marginal surface of the front panel. The front panel may have uneven patterns on at least one side of the surfaces of the front panel, and may also include an intermediate synthetic resin plate between the conductive mesh and the transparent resin plate, as well as a decorative portion between the intermediate synthetic resin plate and the transparent resin plate. In addition, the front panel may contain a conductive film, which is in contact with the conductive mesh in a sheet form on at least one side of the marginal surface of the front panel.
