A drying device for drying a base plate comprising a substrate, a pixel electrode layer and a light-emitting functional layer solution, wherein the pixel electrode layer is disposed on the substrate, and the light-emitting functional layer solution is formed on the pixel electrode layer,
- the drying device comprising:
- a chamber;
- an evacuation member, wherein the evacuation member is arranged on the chamber to evacuate the chamber;
- and
- a conductive member, wherein the conductive member is provided in the chamber, and the conductive member is electrically connectable to the pixel electrode layer to form a drying stage electric field on the pixel electrode layer.
