A high quality and highly reliable plasma display panel having a simple structure where it is possible to stably secure a uniform removal of impurities through the discharge of air from the inside of the panel is provided. An airtight space between a front surface substrate 11 and a rear surface substrate 21 is a space surrounded by a sealing portion 45 in rectangular frame form. This airtight space is divided into two small airtight spaces, space A and space B, which are isolated from each other by one dividing wall 35 formed in the airtight space. The dividing wall 35 is formed so as to pass through the point of L/2 of each long side in a partition formed region 32 when the length of the long sides of the partition formed region 32 is denoted as L. Furthermore, the rear surface substrate 21 is provided with two air holes 38 and 39 so that the space A and the space B in the panel 10 are connected to the outside of the panel 10. End portions of air pipes 41 and 42 are connected to air holes 38 and 39, respectively.
