Disclosed herein is a composition for electrodes that enables a firing process in air at a temperature of 600&#xb0; C. or less and does not cause an increase in absolute resistance and a substantial variation of the resistance even when the composition is repeatedly subjected to the firing process. The composition for electrodes comprises: about 5 to about 95% by weight of aluminum powder, the aluminum powder having a particle size distribution of about 2.0 or less as expressed by the following Equation (1) and having D50 in the range of about 0.1 &#x3bc;m&#x2266;D50&#x2266;about 20 &#x3bc;m; about 3 to about 60% by weight of an organic binder; and the balance of a solvent:Particle size distribution=(90&#x2212;10)/50&#x2003;&#x2003;(1) An electrode and a PDP fabricated using the composition are also disclosed.

Disclosed herein is a composition for electrodes that enables a firing process in air at a temperature of 600&#xb0; C. or less and does not cause an increase in absolute resistance and a substantial variation of the resistance even when the composition is repeatedly subjected to the firing process. The composition for electrodes comprises: about 5 to about 95% by weight of aluminum powder, the aluminum powder having a particle size distribution of about 2.0 or less as expressed by the following Equation (1) and having Din the range of about 0.1 &#x3bc;m&#x2266;D&#x2266;about 20 &#x3bc;m; about 3 to about 60% by weight of an organic binder; and the balance of a solvent:Particle size distribution=()/&#x2003;&#x2003;(1) wherein D, D, and Drepresent particle diameters at 10%, 50% and 90% points on an accumulation curve of a particle size distribution when the total weight is 100%. An electrode and a PDP fabricated using the composition are also disclosed.

A composition for fabricating an electrode includes an organic binder and a conductive filler. About 3 to about 60 wt. % of the composition is the organic binder, about 5 to about 95 wt. % of the composition is the conductive filler, the conductive filler includes predominantly aluminum, the conductive filler has a flake shape, and the conductive filler has an average thickness of about 0.05 &#x3bc;m to about 0.75 &#x3bc;m.
