Patent ID: 7357981

Claim:
A plasma display panel comprising an optical filter comprising a transparent support having provided at least on one side of the support a filter layer containing a dye and a polymer binder, wherein the filter layer has an absorption maximum in the range of wavelength of from 500 to 620 nm, wherein an antireflection layer having an antireflection property to visible light is provided on the side opposite to the side on which the filter layer is provided when the filter layer is provided on either one side, and the antireflection layer is provided on either one side when the filter layers are provided on both sides, and said transparent support comprises a biaxially stretched film having a thickness of from 10 to 500 μm, wherein at least one side of said transparent support is provided with an undercoat layer comprising a polymer having a glass transition temperature of from −60° C. to 60° C., and wherein the undercoat layer provided on the transparent support comprises a first undercoat layer contiguous to the transparent support comprising a styrene-butadiene-based copolymer and a second undercoat layer comprising an acrylic-based resin.
