A fabrication method for a display panel and dielectric configuration applied thereto is provided according to the present invention. The dielectric configuration of the display panel is applicable at atmospheric pressure and to a lower substrate having a surface formed with a dielectric. The fabrication method includes forming at least one lateral line segment and a plurality of longitudinal line segments on the surface of the lower substrate, thereby enabling a process of dispensing dielectric to be performed thereon at atmospheric pressure, and accordingly overcoming the drawbacks of the prior art.
