Abstract:
A method of forming an emission layer by using droplets and an emission part on which charges with opposite polarities are induced, a method of manufacturing an organic light emitting display device including the emission layer, and the organic light emitting display device thereof, the method includes inducing charges having a first charge polarity on emission portions by facing a surface of a mask and a surface of a substrate, contacting the charge inducing units of the mask to the emission portions of the substrate, and then separating the mask from the substrate, supplying droplets exhibiting a second and opposite charge polarity to the substrate and forming the emission layer by allowing droplets exhibiting the second charge polarity to be attracted to and move to the emission portions exhibiting the first charge polarity.
