  • Method of manufacturing organic light emitting display panel
    Patent number: 9142805
    Abstract: A method of manufacturing an organic light emitting display panel forming a protective insulating film in a luminescent region without causing defects in a pattern is disclosed. The method of manufacturing an organic light emitting display panel includes forming a substrate having a luminescent region and a pad region, simultaneously forming a light emitting cell in the luminescent region and an organic pattern in the pad region, forming a protective insulating film over the substrate, bonding the substrate provided with the protective insulating film and the sealing substrate using an adhesive film formed in a region corresponding to the luminescent region, cutting the bonded substrate provided with the protective insulating film and the sealing substrate into a plurality of unit panels to expose the pad region, and removing the protective insulating film and the organic pattern in the exposed pad region.
