<p>A technique for achieving an exhaust path the exhaust efficiency of which is high at low cost, and achieving a high quality panel by preventing unevenness in a panel surface. In a PDP, a discharge space defined by a division wall (8) is formed between a first substrate (102) and a second substrate (101), a display region composed of a cell group is arranged corresponding to the defined portion, a groove (70B) is formed in the plane surface of the first substrate (102), the division wall (8) is provided on the plane surface including the groove (70B), the division wall (8) has a height difference (H4) in accordance with the region of the groove (70B), and the exhaust path is constituted of a space (80B) from the second substrate (101) created by the height difference (H4).</p> |
