Abstract
An organic light emitting display device is provided. Thin film transistors may be located on a substrate. An insulating interlayer having a first contact hole to a third contact hole may be disposed on the substrate. First electrodes electrically connecting the thin film transistors may be located on the insulating interlayer and sidewalls of the first to the third contact holes. A pixel defining layer may be disposed on the insulating interlayer, portions of the first electrodes and the sidewalls of the first to the third contact holes. Light emitting structures may be disposed on the first electrodes in pixel regions. A second electrode may be located on the light emitting structures. Planarization patterns may be disposed on the pixel defining layer to fill the first and the second contact holes. A spacer may be disposed on the pixel defining layer to fill the third contact hole.
