Abstract
Disclosed is an organic light emitting display device including a thin film transistor on a substrate, a planarization layer on the thin film transistor, a contact hole passing through the planarization layer to expose a source or drain electrode of the thin film transistor, a first electrode on the planarization layer, the first electrode being connected to the source or drain electrode of the thin film transistor through the contact hole, a hole between the first electrode and another first electrode adjacent thereto, the hole being a recessed portion of the planarization layer, a pixel defining layer covering the first electrode passing through the contact hole and the planarization layer disposed in the hole, a light emitting layer on the first electrode and the pixel defining layer, and a second electrode on the light emitting layer.
