Abstract
The invention provides a plasma display panel having improved luminous efficiency. The improved luminous efficiency may result in part from at least the configuration and/or arrangement of facing sustain and scan electrodes. In one embodiment, the electrodes may have concave portions that are selectively formed at locators where the electrodes intersect barrier ribs that separate adjacent discharge cells of different colors. This configuration may reduce the charge distribution around the portions where the concave are formed, and may also prevent erroneous discharge from being transferred to adjacent discharge cells. The principles of the invention may be used to produce or light density PDP that increases luminous efficiency and decreases a discharge firing voltage.
