Abstract
Disclosed are a light emitting panel, a display apparatus, and a method for manufacturing the light emitting panel. The light emitting panel includes: a substrate, at least two electrode layers arranged on one side of the substrate, a light emitting layer between the electrode layers. An interfacial modification layer is arranged on one side of at least one of the electrode layers facing the light emitting layer. The interfacial modification layer includes: a polycyclic structure, a first electriferous group connected to a side of the polycyclic structure away from the light emitting layer, a second electriferous group connected to a side of the polycyclic structure facing the light emitting layer. Charges of the first and second electriferous group are different, so that the interfacial modification layer has a dipole moment, therefore a work function of the electrode layers in contact with the interfacial modification layer is adjusted.
