Abstract: A lighting apparatus of the present disclosure includes an organic light emitting diode formed by a first electrode, an organic light emitting layer, and a second electrode on a first substrate and configures the first electrode by a transparent conductive material having an electrical resistance of 2800 to 5500Ω in each pixel. Therefore, even though the first electrode and the second electrode are in contact with each other to remove the electrical resistance by the organic light emitting layer in the pixel, the overcurrent is suppressed from being applied to the pixel by the electrical resistance of the first electrode. Further, at least one conductive pattern formed of a low electrical resistance transparent conductive material which is connected to the first electrode in the pixel is disposed to suppress the degradation of the luminance by the first electrode having a high electrical resistance.
