Patent ID: 7230592

Claim:
An organic light emitting display device, comprising: a substrate SGP; a plurality of drain lines DL; a plurality of current supply lines PL; a plurality of scanning signal lines GL formed on a layer lower than the a plurality of drain lines DL or the plurality of current supply lines PL; and a plurality of pixels; each of the pixels formed in accordance with an intersection between the drain line DL and the scanning signal line GL, comprising: a lower electrodes ITO formed on the substrate; an insulating film BMP formed on the lower electrode, the insulating film comprising an opening with an edge formed on the lower electrode; an organic light emitting layer OCT formed inside of the opening and on the insulating film; an upper electrode CM formed on an organic light emitting layer; a first active switching element SW 1 controlled by the scanning signal line; and a second active element DT controlling a current flowing between of the lower electrode and the upper electrode, the lower electrode ITO being connected to the current supply line PL via the second active switching element, wherein a first electrode C 1 or C 2 is formed under the current supply line PL, extends along the current supply line PL, and comprises titanium or tungsten, and wherein a second electrode layer CSi is formed under the second electrode C 1 or C 2 , extends along the second electrode C 1 or C 2 , and comprises poly silicon.
