Abstract: A plasma display panel (PDP) designed to reduce the amount of external light that is reflected. This is accomplished by having some phosphor material on portions of the tops of the barrier ribs outside the discharge cells.

By reducing external light reflection, the contrast of the image is improved. This can be achieved while still preventing crosstalk between neighboring discharge cells.
