Abstract
An organic light-emitting display device including a driving element including an active pattern and a gate electrode, an insulation layer covering the driving element, a first diode electrode disposed on the insulation layer and electrically connected to the driving element, a pixel-defining layer disposed on the insulation layer and including a side surface defining an opening overlapping at least a portion of the first diode electrode, an edge-compensation part including an organic material and disposed in a peripheral area of the opening, an organic light-emitting layer disposed on the first diode electrode and the edge-compensation part, and a second diode electrode disposed on the organic light-emitting layer, in which the edge-compensation part includes an inclined surface contacting the organic light-emitting layer, and a taper angle of the inclined surface of the edge-compensation part is less than a taper angle of the side surface of the pixel-defining layer.
