Abstract
A PDP has a front and back substrates with a space between them. Barrier ribs in the space define discharge space groups. Each group has first, second and third discharge spaces. Each discharge space has an upper and a lower opening. Air-locking ribs seal the lower opening of the first discharge space, the upper opening and lower openings of the second discharge space, and the upper opening of the third discharge space. A first wall and the adjacent air-locking ribs defines a first channel which is accessible through each of the upper openings of the first discharge spaces. A second wall and the adjacent air-locking ribs defines a second channel which is accessible through each of the lower openings of the third discharge spaces. First, second and third gases respectively fill the first, second and third discharge spaces to emit different colored light.
