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.

Abstract: A method for forming a coating film on an internal surface of an elongated tube, includes longitudinally holding the elongated tube, applying a coating solution to the internal surface of the elongated tube; and drying the coating solution while carrying out a heat process for sequentially heating the elongated tube by using a heat source. The heat process includes adjusting the descending rate of the heat source so that a through-hole in the elongated tube is clogged with the coating solution whose viscosity is reduced by heating of the heat source, and sucking the through-hole in the elongated tube from the lower side thereof so that a portion of the through-hole that is clogged with the coating solution moves downwards along the elongated tube.
