Abstract
The present disclosure discloses a manufacturing method of organic light emitting device, and the steps of the manufacturing method comprises: manufacturing a bottom electrode on a base substrate; manufacturing an organic electro-emitting assembly on the bottom electrode by evaporation techniques and lithography techniques; and manufacturing a top electrode on the organic electro-emitting assembly. An organic light emitting device manufactured by the aforementioned method is further disclosed in the present invention. Hole transport layers corresponded to every emitting layers is manufactured by lithography technologies in the present disclosure; therefore, no fine metal mask is needed in use to reduce production cost and time; furthermore, properties of the organic light emitting device is increased simultaneously.
