摘要:
A display filter includes a base film disposed on a display panel. The base film includes a phototransmissive unit having a constant horizontal cross-sectional area, and a light absorbing unit which includes a light absorbing material and surrounds the phototransmissive unit. A plasma display panel (PDP) may include the display filter. The display filter may improve ambient contrast by increasing the transmittance of light emitted by a display panel and by blocking externally incident light.

An optical filter wherein a hard coating layer and an electromagnetic shielding layer are integrally formed and a method of manufacturing the optical filter. The optical filter includes a base film, and a hard coating layer formed on one surface of the base film, the hard coating layer having conductive substances positioned in a region adjacent to the base film. The method includes preparing a light-transmissive base film; coating a liquid hard coating raw material on one surface of the base film, the hard coating raw material having conductive substances mixed therewith; and curing the hard coating raw material in the state that the conductive substances are concentrated on a region adjacent to the base film, and the hard coating raw material is formed between and on the conductive substances.
