Plasma display panel and method of manufacturing partitions thereof

A plasma display panel comprising:

• a front glass substrate and a rear glass substrate coupled to each other by a sealing material coated at edges of said substrates;
• first and second electrodes formed on opposing inner surfaces of said front and rear glass substrates so as to cross each other;
• a dielectric layer formed on each of the opposing inner surfaces of said front and rear glass substrates to cover said first and second electrodes;
• partitions formed on an upper surface of said dielectric layer of said rear glass substrate;
• red, green and blue fluorescent substances coated between adjacent ones of said partitions;
• and
• a non-light emitting zone filling portion filling a non-light emitting zone defined between an outermost one of said partitions and the sealing material, said non-light emitting zone filling portion being disposed close to said outermost partition and comprising a material used for one of said partitions,
• wherein
• an empty space is defined between the sealing material and said non-light emitting zone filling portion, and
• said non-light emitting zone filling portion covers end portions of said first electrodes.

A method of manufacturing partitions for use in a plasma display panel comprising:

• coating a partition material on an upper surface of a dielectric layer disposed on a glass substrate having electrodes in a predetermined pattern;
• forming a cured pattern of a dry film resist to shield partition material portions designated to form partitions and portions corresponding to a non-light emitting zone between an outermost one of the partitions and a sealing material, said forming the cured pattern comprising
• coating the dry film resist on an upper surface of the coated partition material,
• exposing the dry film resist, and
• developing the exposed dry film resist;
• and
• partially removing the partition material by ejecting abrasion particles at a high speed using the cured pattern as a mask.

A plasma display panel, comprising:

• a front glass substrate having first electrodes over which a first dielectric layer is formed;
• a rear glass substrate disposed opposite said front glass substrate, said rear glass substrate having second electrodes over which a second dielectric layer is formed, the second electrodes not being parallel with the first electrodes;
• a seal connecting corresponding edges of said front and rear glass substrates;
• partitions formed on an upper surface of the second dielectric layer between the edges of said rear glass substrate;
• a fluorescent substance coated between said partitions;
• and
• a non-light emitting zone filling portion disposed between an outermost one of said partitions and said seal so as to prevent a discharge of the first electrodes in a space between said outermost partition and said seal.

A method of manufacturing a plasma display panel, comprising:

• providing a front glass substrate having first electrodes over which a first dielectric layer is formed;
• providing a rear glass substrate disposed opposite said front glass substrate, said rear glass substrate having second electrodes over which a second dielectric layer is formed, the second electrodes not being parallel with the first electrodes;
• forming partitions and a non-light emitting zone filling portion, the partitions and non-light emitting zone filling portions being formed on the second dielectric layer;
• coating a fluorescent substance between the formed partitions;
• forming a seal connecting corresponding edges of the front and rear glass substrates, where the non-light emitting zone filling portion is disposed between an outmost one of the partitions and the seal so as to prevent a discharge of the first electrodes in a space between the outermost partition and the seal.

A plasma display panel, comprising:

• a front glass substrate having first electrodes over which a first dielectric layer is formed;
• a rear glass substrate disposed opposite said front glass substrate, said rear glass substrate having second electrodes over which a second dielectric layer is formed, the second electrodes not being parallel with the first electrodes;
• a seal connecting corresponding edges of said front and rear glass substrates;
• partitions formed on an upper surface of the second dielectric layer between the edges of said rear glass substrate, an outermost one of the partitions extending to said seal so as to prevent a discharge of the first electrodes in a space between said outermost partition and said seal;
• and
• a fluorescent substance coated between said partitions.
