Patent ID: 8077395

Claim:
A display device configured to output an image to an observer side, comprising: a plasma display panel; and a layered sheet stacked on an image output side of the plasma display panel directly, wherein the layered sheet has a plurality of layers that control light emitted from the plasma display panel to emit the light to the observer side, at least one of the plurality of layers is a base material layer, one layer disposed on the observer side of the base material layer is an optical functional sheet layer, which comprises: prisms being arranged in parallel along the sheet surface of the layered sheet whereby light can be transmitted; and light-absorbing parts being arranged in parallel between the prisms whereby light can be absorbed, the light-absorbing part contains light-absorbing particles with an average particle of 1 μm or more one layer disposed on the plasma display panel side surface of the base material layer is an adhesive layer, the layered sheet has a layer that blocks electromagnetic waves and/or a layer that corrects color tone, and the prism of the optical functional sheet layer in a cross section of the optical functional layer has a trapezoidal shape whose long lower base is located at the plasma display panel side, and short upper base is located at the observer side.
