An organic light emitting display (OLED) includes a substrate, first and second driving units positioned on the substrate, a first light emitting diode (LED) connected with the first driving unit and including a first organic light emitting layer and a second emitting diode electrically connected with the second driving unit and including a second organic light emitting layer. The second emitting diode is positioned on the first emitting diode.

Organic light emitting display

An improved organic electroluminescent device is provided. The device may include a protection layer provided on non-light-emitting regions of a panel to prevent reflection of external light. The protection layer may include an optical filter used in combination with a black insulator. The protection layer may provide for improved reflectance and transmissivity, and improved brightness without a commensurate reduction in contrast.

Organic electroluminescent device with black insulator

Provided is an organic light emitting device comprising: a substrate; and a plurality of sub-pixels, each sub-pixel comprising a thin film transistor formed on the substrate; a planarization layer formed on the thin film transistor, and having a contact hole exposing a portion of a source electrode or a drain electrode of the thin film transistor; a contact electrode formed on the planarization layer, and electrically connected with the source electrode or the drain electrode of the thin film transistor through the contact hole; a first electrode spaced apart from the contact electrode, the first electrode formed on the planarization layer; an insulating layer formed on the first electrode and the contact electrode, the insulating layer comprising a first opening exposing a portion of the first electrode and a second opening exposing a portion of the contact electrode; a light emitting layer formed in the first opening; a second electrode formed on the light emitting layer and electrically connected with a portion of the contact electrode through the second opening.
