摘要

PROBLEM TO BE SOLVED: To securely generate gas discharge in the entire discharge space in aging and to reduce impurities remaining in the discharge space by providing dummy electrodes arranged parallel with one another for at least one of multiple scanning electrode couples and by not covering one end of each of the dummy electrodes with a dielectric layer. SOLUTION: Aging dummy electrodes 13 each comprise one transparent electrode body film or one metal film, and is arranged for every couple of multiple scanning electrode couples (X, Y). Each of the dummy electrodes 13 straddles respective picture elements of adjacent scanning lines, and each discharge space 10 right under them which is defined by adjacent barrier plate 7 abuts on boundary spaces between identically-colored unitary light emission regions EU adjacent to each other. In order to continue gas discharge even if local disconnection occurs in the dummy electrode 13 in aging, an external connection terminal part on the common electrode Y side of the dummy electrode 13 is exposed without covering it with a dielectric layer like one end of the electrode 13 and led to the outside of a frame of a low melting point glass layer.
