A glass frit includes at least three metal oxides selected from the group of lead oxide, silicon oxide, tellurium oxide, bismuth oxide, zinc oxide, and tungsten oxide, wherein the glass frit exhibits a phase transition peak in the range of about 300° C. to about 600° C. on a cooling curve obtained via an TG-DTA analysis while a mixture of the glass frit and silver powder, obtained by mixing the glass frit with the silver powder in a weight ratio of 1:1, is cooled at a cooling rate of 10° C./min, after heating the mixture to 850° C. at a heating rate of 20° C./min and held there for a wait-time of 10 minutes.
