Abstract

A method for manufacturing a display panel, and a display device are disclosed. The method for manufacturing a display panel includes: providing a TFT substrate; dispersing graphene and metal nanowires in a hydrophilic solvent to form a hydrophilic conductive ink; applying the hydrophilic conductive ink onto the TFT substrate to form a composite electrode layer; forming, on the composite electrode layer, a pixel defining layer having a plurality of openings at least partially exposing the composite electrode layer; applying hydrophilic organic ink into the plurality of openings of the pixel defining layer to form an organic layer; drying the composite electrode layer and the organic layer to form a first electrode and an organic light emitting structure; and forming a second electrode on the organic light emitting structure and the pixel defining layer.
