Abstract
Provided are an organic light-emitting device that includes a light-emitting layer interposed between a first electrode and a second electrode and a method of manufacturing the same. The light-emitting layer includes a mixed host of a naphthyl anthracene-based compound and a bianthracene-based compound and a dopant. The use of the mixed host of a naphthyl anthracene-based compound and a bianthracene-based compound and a dopant to form the light-emitting layer results in trapping of charges in the light-emitting layer. As a result, the organic light-emitting device is more stabilized and thus has a longer lifetime, excellent color characteristics, and high efficiency.
