Abstract
Barrier ribs of the second type (50) of the same height and material as barrier ribs of the first type (29) are formed on a second substrate in parallel with each other along a first direction (D1) to which display electrodes XE and YE extend. Further, phosphors (28) adhere to both side surface portions (50W3 and 50W4) of the barrier ribs of the second type (50). This achieves a surface discharge type PDP capable of reducing a loss of ultraviolet rays due to repetition of the self absorption and emission of ultraviolet rays, and preventing the leakage of luminescence and discharge to adjacent display lines.

A method of manufacturing a surface discharge type plasma display panel comprising steps of:
- (a) providing a second substrate which specifies a plurality of discharge spaces filled with discharge gas along with a first substrate, said second substrate comprising a plurality of address electrodes extending along a second direction;
- (b) on said second substrate, at the same time, forming a plurality of barrier ribs of a first type extending in parallel with each other at first intervals along said second direction so that each of said plurality of address electrodes is located between adjacent barrier ribs of the first type out of said plurality of barrier ribs of the first type, and a plurality of barrier ribs of a second type extending in parallel with each other at second intervals along a first direction orthogonal to said second direction so as to intersect with said plurality of barrier ribs of the first type;
- and
- (c) adhering phosphors to said second substrate sandwiched between adjacent barrier ribs of the first type out of said plurality of barrier ribs of the first type, a first side surface poriton of one of said adjacent barrier ribs of the first type, and a second side surface portion of the other of said adjacent barrier ribs of the first type facing to said first side surface portion.
