Abstract
A plasma display panel in which projections are formed in grooves between partitions and phosphor layers are provided on the projections so as to increase the area where phosphor adheres and thereby to increase the luminance. A couple of substrates are opposed to each other to form a discharge space. Band-like partitions partitioning the discharge space are arranged on the back or front substrate. Wall-like projections lower than the partitions and high enough to increase the area where phosphor layers are formed are provided in the region where the discharge space is formed in the long grooves between the partitions or around the discharge space. Phosphor layers are formed in the grooves between the partitions including the wall-like projections. A method for producing such a plasma display panel is also disclosed.
