Abstract
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.
Claims10
An organic light emitting display comprising:
- a substrate;
- a first and a second driving units positioned on the substrate so that the first and the second driving units are separated from each other;
- an first insulation layer positioned between the first and second driving units to isolate the first driving unit from the second driving unit;
- a first light emitting diode positioned on the first insulation layer, electrically connected with the first driving unit, and comprising a first organic light emitting layer;
- a second emitting diode positioned on the first light emitting diode, and electrically connected with the second driving unit, the second light emitting diode comprising a second organic light emitting layer and an upper electrode positioned on the second organic light emitting layer, and
- a connection layer positioned on the second driving unit, extending from the second driving unit to the upper electrode along the first light emitting diode and the second light emitting diode, and electrically connecting the upper electrode of the second emitting diode to the second driving unit,
- wherein the first emitting diode is positioned on the first insulation layer, and the second emitting diode is positioned on the first emitting diode,
- wherein a height of the first and the second driving units is higher than that of the first insulation layer.
