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

Provided is an organic light emitting display, comprising a substrate; a driving unit formed over the substrate; a planarization layer formed over the driving unit, the planarization layer comprising a normal tapered edge portion; and an emission unit formed over the planarization layer to be electrically connected to the driving unit.

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.
