Abstract

A plasma display panel includes front glass substrate and rear glass substrate disposed opposite to each other so as to form an image display area and an image non-display area. The image non-display area includes a sealing portion in which glass substrates are sealed at a periphery thereof by a seal layer. At least one of front glass substrate and rear glass substrate has a thickness of 0.5 mm or more and 2.0 mm or less. The seal layer is made of a glass material having a softening point temperature 30° C. through 70° C. lower than the sealing temperature at which the periphery of front glass substrate and rear glass substrate are sealed by the seal layer.

Claims (22)

1 - 4 . (canceled)

5 . A method for manufacturing a plasma display panel, comprising:

forming an image display area and an image non-display area by disposing a pair of glass substrates so as to be opposite to each other, the image non-display area including a sealing portion; and

sealing, using a sealing layer, a periphery of the glass substrates of the image non-display area,

wherein the glass substrates has a thickness of at least 1.5 mm and at most 1.8 mm,

wherein the sealing layer is made of a sealing material including a glass material, the sealing material having a softening point temperature 30° C. through 70° C. lower than a sealing temperature at which the periphery of the glass substrates is sealed by the sealing layer, and

wherein the sealing material has a softening point temperature of 400° C. or more.

6 . The method for manufacturing a plasma display panel of claim 5 , wherein the sealing temperature is 470° C.

7 . A method for manufacturing a plasma display panel, comprising:

forming an image display area and an image non-display area by disposing a pair of glass substrates so as to be opposite to each other, the image non-display area including a sealing portion; and

sealing, using a sealing layer, a periphery of the glass substrates of the image non-display area,

wherein the glass substrates has a thickness of at least 1.2 mm and at most 1.8 mm,

wherein the sealing layer is made of a sealing material including a glass material, the sealing material having a softening point temperature 40° C. through 70° C. lower than a sealing temperature at which the periphery of the glass substrates is sealed by the sealing layer, and

wherein the sealing material has a softening point temperature of 400° C. or more.

8 . The method for manufacturing a plasma display panel of claim 7 , wherein the sealing temperature is 470° C.

9 . A method for manufacturing a plasma display panel, comprising:

forming an image display area and an image non-display area by disposing a pair of glass substrates so as to be opposite to each other, the image non-display area including a sealing portion; and

sealing, using a sealing layer, a periphery of the glass substrates of the image non-display area,

wherein the glass substrates has a thickness of at least 0.6 mm and at most 1.8 mm,

wherein the sealing layer is made of a sealing material including a glass material, the sealing material having a softening point temperature 60° C. through 70° C. lower than a sealing temperature at which the periphery of the glass substrates is sealed by the sealing layer, and

wherein the sealing material has a softening point temperature of 400° C. or more.

10 . The method for manufacturing a plasma display panel of claim 9 , wherein the sealing temperature is 470° C.
