Abstract

An organic light emitting diode and a manufacturing method thereof, and a display panel are provided. The organic light emitting diode includes an anode layer, a hole transport layer, and a hole injection layer located between the anode layer and the hole transport layer. The hole injection layer has a work function of which a value increases in a direction from the anode layer toward the hole transport layer, and thus, an injection barrier between the anode layer and the hole transport layer is reduced and thereby improving the luminescent efficiency of the organic light emitting diode.
