Plasma display panel and method of manufacturing the same

A plasma display panel including a plurality of row electrode pairs extending in a row direction and arranged in a column direction to respectively form display lines and a dielectric layer overlaying the row electrode pairs on a backside of a front substrate, and a plurality of column electrodes extending in the column direction and arranged in the row direction to constitute unit light emitting areas in a discharge space at respective positions, corresponding to intersections of the column electrodes and the row electrode pairs, on a surface of a back substrate facing the front substrate with a discharge space in between, each row electrode of said row electrode pair being made up of transparent electrodes formed to oppose the corresponding transparent electrode via a predetermined discharge gap, and a bus electrode extending in the row direction and connected an end of the transparent electrode situated opposite to the discharge gap, said plasma display panel comprising:

• an additional portion formed on a backside of said dielectric layer to oppose the back-to-back arranged bus electrodes of the adjacent row electrode pairs in the column direction and a portion surrounded by the back-to-back bus electrodes and to protrude toward the discharge space, and
• a light-shield layer formed on at least a portion of said additional portion opposing the portion surrounded by said back-to-back bus electrodes.

A method of manufacturing a plasma display panel comprising steps of:

• a process for forming the row electrodes, each including transparent electrodes and the bus electrode, in pair on a front substrate to extend in a row direction and be arranged in a column direction;
• a process for forming a dielectric layer to overlay the row electrode pairs;
• and
• a light-shield layer forming process for forming a light-shield layer on a portion of a dielectric layer opposing a portion situated between the row electrode pairs and surrounded by the respective bus electrodes.
