1. A method of fabricating a display panel, comprising:
providing a substrate;
disposing a pixel electrode layer on the substrate;
forming a light-emitting functional layer solution on the pixel electrode layer to form a base plate;
transferring the base plate into a chamber;
forming a drying stage electric field on the pixel electrode layer;
drying the base plate; and
evacuating the chamber under the drying stage electric field to discharge a solvent in the light-emitting functional layer solution to form a light-emitting functional layer.
