Abstract:
1. A method of manufacturing an organic light-emitting display device, the method comprising the steps of: forming a plurality of metal particles attached to a transparent substrate by stacking a metal thin film on the substrate and annealing the metal thin film so as to agglomerate a metal of the metal thin film; forming a buffer layer on the substrate so as to contain the metal particles; forming an active layer, which includes a source region and a drain region, on the buffer layer; forming a gate insulating film on the substrate and the active layer; forming a gate electrode on the gate insulating film to overlap a channel region of the active layer; forming an interlayer insulating film on the gate insulating film to cover the gate electrode; forming a source electrode and a drain electrode, which are connected to the source region and the drain region, respectively, on the interlayer insulating film; forming a passivation layer on the interlayer insulating film and on the source electrode and the drain electrode; forming a transparent first electrode, which is connected to one of the source electrodes and the drain electrodes, on the passivation layer; forming a pixel defined layer, which exposes a predetermined region of the first electrode, on the passivation layer and the first electrode; and forming a plurality of metal nanoparticles attached to the first electrode by stacking a metal thin film on the predetermined region of the first electrode, the predetermined region of the first electrode being exposed by the pixel defined layer, and by annealing the metal thin film.
