A method of manufacturing an organic EL element operating at low voltage to emit light at high intensity comprises: a first step of forming, on an anode, a hole injection layer including metal oxide; a second step of irradiating the hole injection layer with ultraviolet light, the ultraviolet light having a wavelength greater than a wavelength at which oxygen molecules decompose and yield oxygen radicals; a third step of forming functional layers containing organic material on or above the hole injection layer after the second step, the functional layers including a light-emitting layer; and a fourth step of forming a cathode on or above the functional layers. |
