Abstract: An organic light emitting display panel may include a plurality of thin film transistors on a substrate, an insulating interlayer on the thin film transistors, a plurality of first electrodes on a portion of the insulating interlayer electrically connected to the thin film transistors, a plurality of metal lines on a portion of the insulating interlayer, a pixel defining layer on a portion of the insulating interlayer and a portion of the first electrodes, a plurality of organic light emitting structures on the first electrodes in the pixel area, a second electrode on the organic light emitting structures, and a spacer on the pixel defining layer. The insulation interlayer may partially expose electrodes of the thin film transistors. The pixel defining layer may define a pixel area by partially exposing the first electrodes, and an exposed area of the insulating interlayer by partially exposing the insulating interlayer.
