Abstract:
1. A method of manufacturing an organic light-emitting display device, the method comprising: forming a plurality of thin film transistors (TFTs) on a substrate; forming a plurality of organic light emitting diodes (OLEDs), each of the OLEDs comprising a first electrode having a portion exposed by a pixel defining layer (PDL) on the TFTs, an organic layer on the exposed portion of the first electrode and comprising an emission layer (EML) configured to emit light having at least one of a plurality of colors, and a second electrode on the organic layer; forming the EML in each of a sub-pixel region with one color and other sub-pixel regions with other colors, the sub-pixel regions being formed by forming openings in the PDL; forming a solution supply unit in the PDL that fluidly communicates with the sub-pixel region with one color; and supplying emission layer raw materials for the plurality of colors to the sub-pixel region with one color and the other sub-pixel regions with other colors via the solution supply unit, thereby forming the EML.
