  • Publication number: 20090078933
    Abstract: An organic light emitting device includes a first electrode disposed on a substrate, a plurality of organic function layers disposed on the first electrode and comprising an emitting layer, and a second electrode disposed on the organic function layers. One of the organic layers includes an inorganic material. This layer may be formed adjacent the first electrode or adjacent the second electrode to form top-emission or bottom-emission structures.

  • Publication number: 20090079332
    Abstract: A light-emitting device includes a substrate with a thin film transistor, an insulating film on the substrate that includes a via hole exposing the thin film transistor, a first electrode on the insulating film and connected to the thin film transistor, an emitting layer on the first electrode, and a second electrode on the emitting layer and including a non-conductive layer and a transparent conductive layer sequentially disposed over the emitting layer. A thickness of the first electrode is a predetermined number of times greater than a thickness of the emitting layer, and a thickness of the second electrode is a predetermined number of times greater than the thickness of the emitting layer.

  • Publication number: 20090066232
    Abstract: An organic light emitting device is disclosed. The organic light emitting device includes a first substrate, an organic light emitting element on the first substrate, a second substrate facing the first substrate, and a seal member attaching the first substrate to the second substrate. The organic light emitting element includes an emitting layer. At least one of layers constituting the emitting layer includes a phosphorescence material. The seal member has an absorptance that lies substantially in a range between 25% and 35% at a wavelength of external light of approximately 305 nm to 330 nm.
