Abstract: A method of manufacturing a light-emitting display device, the method including forming a first electrode on a substrate, the substrate including a plurality of pixel regions divided by a non-pixel region, in each of the pixel regions; forming a pixel defining layer, the pixel defining layer having a plurality of pixel openings, each of the pixel openings exposing the first electrode, on the substrate; forming a hole injection layer on the first electrode; forming a lyophilic layer on the hole injection layer to completely overlap the hole injection layer; forming a hole transport layer on the lyophilic layer; forming a light-emitting layer on the hole transport layer; and forming a second electrode on the light-emitting layer.
