We have prepared two kinds of panels with a change in the sealing atmosphere. for this, air and nitrogen gas were used, respectively. The discharge voltages, Vfxy and Vfay, for the panel sealed in nitrogen gas were 35V and 30V lower, respectively, than those for the panel sealed in air. Moreover, long‐term operation drifts in brightness, discharge voltage and delay time were considerably reduced. In order to find probable explanations to the differences caused by the sealing atmosphere, the protective layers were examined with analysis tools like SEM, CL and XPS. From this analysis, no clear explanation was obtained.
