ABSTRACT:
The present invention provides an organic light emitting device, wherein an electron injecting electrode, at least one organic material layer including a light emitting layer, and a hole injecting electrode are laminated; and an inorganic insulating layer formed from the materials having a band gap of 3.3 eV or more, and a band offset of 0.45 eV or less, is provided between the electron injecting electrode and the organic material layer; and a method for preparing the same.
