    摘要: An organic light-emitting device includes a substrate; a first electrode; a second electrode facing the first electrode; an organic layer disposed on the first electrode; and an emitting layer interposed between the organic layer and the second electrode. The concentration of inorganic impurities within the organic layer is 1000 ppb or less. The organic light-emitting device has high light-emitting efficiency, low driving voltage, high brightness, and long life span.
