Abstract: Provided is a display panel including a loop-shaped conductive path which is manufactured by performing a conductive ink jetting process and a high-degree vacuum removal process to effectively vaporizing a solvent in a conductive ink line at lower temperature than the boiling point at atmospheric pressure of the solvent. The conductive path manufactured as such does not allow a stain or a trace, such as a pull-back region, to be left around the conductive path. Thus, it is possible to obtain the loop-shaped conductive path having an initially intended design without being damaged during a process.
