Abstract

An organic light emitting diode substrate, a method for manufacturing an organic light emitting diode substrate, and a display panel. The organic light emitting diode substrate includes: a base substrate; a pixel defining layer on the base substrate; and an anode, an organic light emitting diode functional layer and a cathode in a pixel region. The pixel defining layer includes a first pixel defining layer, an auxiliary cathode and a second pixel defining layer sequentially stacked, the auxiliary cathode being connected to the cathode.
