We have examined the electrical and optical characteristics of the plasma display panel(PDP) produced by vacuum in-line sealing technology. We found that the luminous efficiency was decreased as the base vacuum level was increased. For the base vacuum level of $1\times10^{-3}$ Torr, the firing voltage was 235V at the discharge gas pressure of 400 Torr and the luminous efficiency was 0.8 lm/W at 180V sustaining pulse. However, for the base vacuum level of $1\times10^{-6}$ Torr, the firing voltage was reduced to 215V and the luminous efficiency was improved to 2.5lm/w. Finally, we demonstrated successfully the operation of tip-less PDP fabricated using vacuum in-line sealing method.

Effects of the evaporation rate of MgO films using electron beam were investigated on the MgO properties and the discharge characteristics of the plasma display panel (PDP). The evaporation rate was changed from $3{\AA}$/sec to $15{\AA}$/sec at a substrate temperature of $300^{\circ}C$. MgO properties such as crystal orientation, surface roughness, contact angle, and film structure were inspected using XPS, AFM, drop shape analysis and SEM. We also studied the relation between MgO properties and PDP discharging characteristics. The minimum firing voltage and maximum efficacy were obtained at evaporation rate of $5{\AA}$/sec. In the MgO film deposited at $5{\AA}$/sec, (200) orientation was most intensive and surface roughness was minimum.
