Abstract:
A plasma display panel comprising:a pair of first and second substrates facing each other and spaced with a discharge space, which are on a display-screen side and on a back side respectively;a plurality of pairs of row electrodes extending horizontally and arranged on an inner surface of the first substrate as corresponding to display-lines respectively, each of said paired row electrodes comprised of a main body portion extending horizontally and projecting portions each projecting from the main body portion toward the other row electrode in the pair in a manner that fellow front ends of the paired projecting portions face each other through a discharge gap;a dielectric layer formed on said row electrodes;a plurality of column electrodes extending vertically and arranged on an inner surface of said second substrate, each of said plurality of column electrodes associated with each of the row electrodes and defining a unit region of light-emission including the discharge gap and an intersection formed wherever one of said column electrodes crosses apart from one of said pair of row electrodes in said discharge space;a plurality of first ribs extending vertically and disposed between said column electrodes to separate said discharge space for each of said unit regions of light-emission;fluorescent layers covering up at least said column electrodes, anda plurality of second ribs provided on said inner surface said second substrate, each second ribs facing an opposite edge portion of said projecting portion to said discharge gap and a portion of the main body portion of the row electrode in the vicinity of said opposite edge, and said second ribs being in contact with said dielectric layer.
