Patent ID: 6987356

Claim:
An active matrix type organic electro-luminescent display (OELD) comprising a pixel having a triode organic electro-luminescent device and a driving semiconductor for driving said triode organic electro-luminescent device; said triode organic electro-luminescent device formed on a substrate having an anode electrode, a cathode electrode arranged opposite to said anode electrode, a luminescent layer interposed between said anode electrode and said cathode electrode and a control electrode positioned at a given level on which one of said anode electrode and said cathode electrode is formed and separated from said one of said anode electrode and said cathode electrode, said control electrode connected to said cathode electrode and having negative or positive potential so as to control flow of holes from said anode electrode and electrons from said cathode electrode to said luminescent layer; and said driving semiconductor positioned on or under said triode organic electro-luminescent device, an insulating interlayer being interposed between said driving semiconductor and said triode organic electro-luminescent device, and said driving semiconductor has one terminal receiving an external power supply and another terminal connected to one of said electrodes of the triode organic electro-luminescent device via a first hole formed in said insulating interlayer so that current of said triode organic electro-luminescent device is controlled.
