AC plasma display device

An AC plasma display device having structure for preventing error-discharges, comprising:

• a transparent front substrate having an array of display electrodes comprising a non-display portion located between the display electrodes,
• a rear substrate comprising an array of data electrodes in a direction perpendicular to the display electrodes and located facing the front substrate and defining a discharge space between said rear substrate and said front substrate,
• a first partition located to form the discharge space between the data electrodes on said rear substrate and to define a gap of the discharge space,
• a barrier located between said partitions on said rear substrate and at a position facing the non-display portion on said front substrate, an upper surface of said barrier being in parallel with a face of said front substrate, a height of said barrier being lower than a height of said partition;
• and
• a second partition located on said front substrate at a position corresponding to said first partition, contacting said first partition at their tops, forming the discharge space and defining a gap of the discharge space with said first partition, wherein
• said barrier has a width corresponding to the non-display portion, and a non-zero difference between the height of said partition and the height of said barrier on said rear substrate is not greater than ⅓ of a distance between display electrodes which adjoin each other and sandwich the non-display portion.
