Abstract
Disclosed herein are an organic light-emitting device having a structure formed by the sequential deposition of a substrate, a first electrode, at least two organic layers and a second electrode, in which the organic layers include a light-emitting layer, and one of the organic layers, which is in contact with the second electrode, is a buffer layer comprising a compound represented by the following formula 1, as well as a fabrication method thereof:wherein R1 to R6 have the same meanings as defined in the specification. The buffer layer makes it possible to minimize or prevent damage to the organic layer, which can occur when forming the second electrode on the organic layer.
