Organic light emitting display devices and methods of manufacturing organic light emitting display devices

An organic light emitting display device comprising:

• thin film transistors on a substrate;
• an insulating interlayer on the thin film transistors, the insulating interlayer having a first contact hole, a second contact hole and a third contact hole, wherein the first to the third contact holes partially expose the thin film transistors, respectively;
• first electrodes disposed on the insulating interlayer and sidewalls of the first to the third contact holes, the first electrodes being electrically connected to the thin film transistors;
• a pixel defining layer disposed on the insulating interlayer, portions of the first electrodes and the sidewalls of the first to the third contact holes, the pixel defining layer defining pixel regions;
• light emitting structures on the first electrodes in the pixel regions;
• a second electrode on the light emitting structures;
• planarization patterns on the pixel defining layer, the planarization patterns filling the first and the second contact holes;
• and
• a spacer on the pixel defining layer, the spacer filling the third contact hole.
