Abstract: A method for manufacturing an organic light emitting display apparatus can include forming a transistor on a substrate; forming a planarization film having a lower contact hole on the transistor; forming a connection electrode electrically connected with the transistor through the lower contact hole on the planarization film; and forming an insulating film having a contact hole on the planarization film on which the connection electrode is patterned. Also, the method can further include forming a first electrode having a contact area covering the contact hole on the insulating film and a protrusion vertically protruded on a boundary surface of the contact hole; forming a fence film on the insulating film on which the first electrode is patterned; forming an organic light emitting layer on the first electrode and the fence film; and forming a second electrode on the organic light emitting layer.
