Patent ID: 8072141

Claim:
A plasma display device, comprising: a plasma display panel (PDP); and an external light shield sheet that absorbs external light incident upon the PDP, wherein the external light shield sheet comprises: a base unit that transmits panel light; and a plurality of pattern units that are formed in the base unit, and that absorb the external light and light emitted from the PDP, wherein each of the plurality of pattern units includes a top, a bottom wider than the top, a first inclined surface connected to the top and to the bottom and a second inclined surface connected to the top and to the bottom, wherein each of the plurality of pattern units contains 2-10 weight % of light absorption particles having an average size of 1 Î¼m or less, wherein the light absorption particles are formed on outer surfaces of the first inclined surface and the second inclined surface, and wherein a refractive index of the pattern units is higher than a refractive index of the base unit.
