Mesh-pattern partitioned plasma display panel
View Patent ↗A plasma display panel is provided in which discharge connection in the column direction is prevented without increasing the number of man-hours in a formation process of a partition and without deteriorating ventilation for an exhaust process. A pattern in a plan view of a partition is made a mesh pattern in which vertical patterns are included at inter-row positions in each column. Each of first vertical walls is positioned at a boundary between columns, each of second vertical walls is arranged at a position away from a boundary between columns for each boundary between rows and each of horizontal walls is positioned at a boundary between rows. In the partition, a height of portions where the first vertical wall crosses the horizontal wall and a height of portions where the second vertical wall crosses the horizontal wall are smaller than a height of the other portions of the partition.
1. A plasma display panel, comprising:
a mesh-patterned partition having a plurality of discharge barrier portions dividing a discharge space into columns of discharge cells and a plurality of inter-row portions dividing the discharge space into rows of the discharge cells, wherein:
each of the inter-row portions of the mesh-patterned partition is a ladder-like pattern including at least two horizontal walls along a row direction and a plurality of inter-row vertical walls disposed between the horizontal walls;
the inter-row vertical wall crosses the horizontal wall at a position away from a cross section of the discharge barrier portion and the horizontal wall;
a height of the inter-row vertical wall varies in a column direction; and
a height of a portion in which the inter-row vertical wall crosses the horizontal wall is lower than a height of an other portion of the inter-row vertical wall.
2. The plasma display panel according to claim 1 ,
wherein the inter-row vertical wall crosses, at one end portion thereof in the column direction, the horizontal wall, and a height midpoint between said one end portion and an other end portion of the inter-row vertical wall is higher than heights of said one end portion and said other end portion.
3. The plasma display panel according to claim 1 , wherein the other portion of the inter-row vertical wall has a height with which to limit spread of discharge between the discharge cells adjacent in the column direction to each other.
4. The plasma display panel according to claim 1 , wherein a height of the horizontal wall varies in a row direction.
5. The plasma display panel according to claim 4 , wherein the height of the horizontal wall in the portion in which the inter-row vertical wall crosses the horizontal wall is lower than the height of the horizontal wall in other portion.
6. The plasma display panel according to claim 4 , wherein the height of the horizontal wall in a portion in which the discharge barrier portion crosses the horizontal wall is lower than the height of the horizontal wall in other portion.
