Patent ID: 7909672

Claim:
A method of manufacturing an organic light-emitting display device comprising: a plurality of pixels each of which is a minimum unit of a picture; a plurality of organic light-emitting devices as each said pixel, said organic light-emitting devices each including: a pair of electrodes comprising a first electrode and a second electrode, wherein the first electrode is disposed on a lower surface of an organic layer and the second electrode is disposed on an upper surface of the organic layer; and current supply lines comprising a first current supply line and a second current supply line, wherein the second current supply line is connected to the second electrode through a contact hole in a display region of each pixel and wherein the first current supply line is connected to the first electrode through one or more driving devices, said method comprising the steps of: forming the organic layer to comprise a plurality of organic light-emitting devices on a substrate; forming a driving layer including the driving devices for driving said plurality of organic light-emitting devices; forming a wiring layer comprising signal lines and scanning lines connected to said driving devices forming the first and second current supply lines on the lower side of said organic layer and on the upper side of said organic layer, respectively, forming the contact hole in an interlayer insulating film formed in the surrounding areas of said current supply lines; and connecting the second electrode to the second current supply line through said contact hole.
