ABSTRACT:
The present invention provides a plasma display device having an even and homogeneous dielectric layer and permitting a small luminance change over time. The plasma display device includes a first substrate, a second substrate disposed facing an inside of the first substrate so as to form a hermetically sealed discharge space therebetween, at least one pair of discharge sustain electrodes which are formed inside the first substrate11and forming a discharge gap therebetween, and the dielectric layer formed inside the first substrate so as to cover the discharge sustain electrodes. The dielectric layer has a low degassing film such that a total amount of degassing when increasing a temperature from room temperature to 1000° C. has hydrogen molecules not exceeding 1×1020particles/cm3and water not exceeding 5×1020particles/cm3.
