Patent ID: 6998781

Claim:
A plasma display device comprising: a plurality of pairs of discharge sustain electrodes formed on the inner side of a first substrate in such a manner as to extend along a first direction while being nearly in parallel to each other; a dielectric layer formed on the inner side of said first substrate in such a manner as to cover said discharge sustain electrodes; and barrier ribs formed on the inner side of a second substrate in such a manner as to form discharge spaces sealed between said first substrate and said second substrate; wherein said barrier ribs have vertical ribs extending along a second direction different from said first direction while being nearly in parallel to each other, and lateral ribs extending along said first direction while being nearly in parallel to each other; notches for communicating spaces surrounded by said vertical ribs and said lateral ribs to each other along at least one of said first direction and said second direction are formed at least in portions of at least one of said vertical ribs and said lateral ribs; and each of said lateral ribs is composed of two or more rows of lateral rib elements; and wherein said vertical ribs formed in such a manner as to extend along said second direction while being nearly in parallel to each other extend not in a straight-line shape but in a meandering shape or a zigzag shape along said second direction, and a discharge space is disposed between said vertical ribs adjacent to each other in such a manner as to extend along both said first direction and said second direction; said lateral rib is formed at a position where the said vertical ribs adjacent to each other become closest to each other; wherein said discharge sustain electrodes are formed from a transparent conductive material.
