Abstract
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.
