Abstract
An embodiment of the present application provides a display panel. The display panel generates an electric field on the pixel electrode. In the display panel provided by the present application, since opposite poles that generate the electric field are specially designed, a distance between the opposite poles that generate the electric field is constant everywhere, thereby improving uniformity of the electric field. Such electric field assisted deposition of a light-emitting functional layer material and drying of the light-emitting functional layer can suppress a coffee ring effect.
