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.
