Abstract: A lighting apparatus according to an embodiment of the present invention includes an organic light emitting device including a first electrode, an organic light emitting layer, and a second electrode formed on a first substrate, wherein the first electrode is formed of a transparent conductive material having a resistance of approximately 2800Ω to 5500Ω in each pixel. Thus, even if the resistance of the organic light emitting layer is removed in a pixel due to a contact between the first electrode and the second electrode, overcurrent may be prevented from being applied to the pixel due to the resistance of the first electrode.
