Abstract
A fabrication method of a display panel and a drying device are provided by the present application. In the display panel of the present application, an electrical field for drying on a pixel electrode layer is used to fix charged groups in a solution of a light-emitting functional layer, which prevents a solvent from driving the movement of the charged groups when the solvent is volatilized, thereby obtaining a light-emitting functional layer with a uniform film thickness. Moreover, the use of the electric field for drying fixes the charged groups so that a drying treatment is performed without strict pumping control during the solvent volatilization process.
