Abstract
A lighting apparatus of the present disclosure may transport a film formed with a plurality of lighting apparatuses between rolls, and place a mask on an entire surface of the film to deposit an organic light emitting material in a state in which a part of the film is blocked to form an organic light emitting layer, and then deposit a metal layer by the same mask to form a second electrode, wherein the organic light emitting layer and the second electrode are not formed in a region where a pad is formed by the mask to open the pad and connect an external signal source thereto. The first electrode may be connected to a first pad and the second electrode may be connected to a second pad to apply a voltage, wherein a part of the organic light emitting layer is laser-etched to form a contact portion, and the second electrode is electrically connected to the second pad.
