ORGANIC LIGHT-EMITTING DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME

摘要

The present invention relates to an organic light-emitting display device and a method of fabricating the same. The device may include a base substrate, a thin-film transistor disposed on the base substrate, an organic light-emitting device including a first electrode connected to the thin-film transistor, an organic pattern disposed on the first electrode, and a second electrode disposed on the organic pattern. The device further includes an auxiliary electrode including a connection part and a non-connection part, the connection part being connected to the second electrode. The width of the connection part may be less than that of the non-connection part, when measured in the direction perpendicular to a current flow.

1. A method of fabricating an organic light-emitting display device, the method comprising:
forming a thin-film transistor on a base substrate; forming a first electrode connected to the thin-film transistor and an auxiliary electrode spaced apart from the first electrode, the auxiliary electrode comprising a connection part and a non-connection part; forming a pixel defining layer, the pixel defining layer exposing portions of the first electrode and portions of the connection part; forming an organic layer on the first electrode, the connection part, and the pixel defining to layer; patterning the organic layer to form an organic pattern; and forming a second electrode on the organic pattern and the pixel defining layer, wherein forming the organic pattern comprises:
applying an electric power to the auxiliary electrode to produce heat from the connection part; andremoving a portion of the organic layer adjacent to the connection part using the heat.
