PURPOSE: An OLED(Organic Light Emitting Diode) manufacturing method and an OLED are provided to interpose a connecting layer in each set of light emitting units, thereby embodying the high definition and the wide viewing angle. CONSTITUTION: An anode is formed in the upper part of a substrate. A lighting emitting unit is positioned in the upper part of a first electrode. The lighting emitting unit comprises a light emitting units and a-1 connecting layers. A cathode is formed in the upper part of the lighting emitting unit. A first light emitting unit is installed in the upper side of the anode. An a-numbered light emitting unit is installed in the lower side of the cathode. The a light emitting units and the a-1 connecting layers are alternately arranged. One or more connecting layers among the a-1 connecting layers comprises a P-type layer installed in a cathode direction and an n- type layer installed in an anode direction.
