ABSTRACT:
A plasma display device disclosed herein is capable of enhancing the contrast of external light, facilitating application of phosphor paste on the bottom of each space surrounded by lattice-like barrier ribs, and reducing a variation in the amount of the phosphor paste applied as much as possible. The lattice-like barrier ribs include lateral ribs extending along a first direction while being nearly in parallel to each other, and vertical ribs extending along a second direction different from the first direction while being nearly in parallel to each other. Each of the lateral ribs is composed of two or more rows of rib elements. Notches for communicating spaces surrounded by the vertical ribs and the lateral ribs to each other in the first direction and/or the second direction are formed at least in portions of the vertical ribs and/or the lateral ribs.
