Abstract
The present invention relates to a transparent conducting film and an organic light emitting device comprising the same. The transparent conducting film according to the present invention has a low surface resistance value, a high front surface transmittance and a low light absorptance. The light emission efficiency of the organic light emitting device according to the present invention may be enhanced by comprising a transparent conducting film having low light absorptance. In particular, the organic light emitting device according to the present invention may additionally comprise an internal light extraction layer to improve the light extraction efficiency, and the loss of light generated by the difference between refractive indices of a transparent electrode and a substrate may be minimized.
