Abstract
A lighting device is provided. The lighting device may include an organic light emitting diode arranged on one surface of a first substrate, the organic light emitting diode including a first electrode, an organic light emitting layer and a second electrode, and the first electrode is made of a transparent conductive material having a resistance value of 2,800-5,500Ω in each pixel, and has light scattering particles dispersed therein. Thus, even when a resistor of the organic light emitting layer is removed from a pixel due to a contact between the first electrode and the second electrode, it is possible to prevent an over current from being applied to the corresponding pixel through a resistor of the first electrode.
