Abstract

A plasma display panel has an image display region( 17 )and a non-image display region formed by facing front glass substrate ( 3 ) to back glass substrate ( 10 ), and has a sealed part ( 18 ) formed by sealing peripheries of the glass substrates in the non-image display region with a seal layer( 19 ). A thickness of at least one of the front glass substrate ( 3 ) and the back glass substrate ( 10 ) is 2.0 mm or less, and an interval between the glass substrates in the sealed part longer than an interval between the glass substrates in the image display region.

Claims (14)

1. A plasma display panel comprising:

an image display region and a non-image display region formed by facing a pair of glass substrates to each other; and

a sealed part formed by sealing peripheries of the pair of glass substrates in the non-image display region with a seal layer,

wherein a thickness of at least one glass substrate of the pair of glass substrates is at least 0.5 mm and no more than 1.8 mm,

wherein an interval between the pair of glass substrates in the sealed part is longer than an interval between the pair of glass substrates in the image display region, and

wherein a distance between a center region of the sealed part and the image display region is at least 20 mm and no more than 30 mm.

2. The plasma display panel of claim 1 ,

wherein a difference between (i) the interval between the pair glass substrates in the sealed part, and (ii) the interval between the pair of glass substrates in the image display region, is at least 10 μm and no more than 50 μm.

3. The plasma display panel comprising:

an image display region and a non-image display region formed by facing a pair of glass substrates to each other; and

a sealed part formed by sealing peripheries of the pair of glass substrates in the non-image display region with a seal layer,

wherein a thickness of at least one glass substrate of the pair of glass substrates is at least 0.5 mm and no more than 1.8 mm,

wherein an interval between the pair of glass substrates in the sealed part is longer than an interval between the pair of glass substrates in the image display region, and

wherein a difference between (i) the interval between the pair of glass substrates in the sealed part, and (ii) the interval between the pair of glass substrates in the image display region, is at least 10 μm and no more than 50 μm.
