A method of manufacturing a light-emitting display device, the method including forming a first electrode on a substrate for each pixel of a plurality of pixels; forming a pixel defining film on the first electrode such that the pixel defining film includes an opening exposing the first electrode; and forming an organic layer on the first electrode, wherein forming the organic layer includes providing an organic solution into the opening of the pixel defining film, and drying the organic solution by performing an exhaust process in a state where an air current is provided by using a drying gas such that the air current is sequentially composed of a position facing the organic solution, a position to which the organic solution is discharged, and a position facing the organic solution.

Method of manufacturing light-emitting display device with reduced pressure drying

Provided are an apparatus for manufacturing an OLED display and a method of manufacturing OLED display. According to another aspect of the present invention, there is provided the method of manufacturing an OLED display which includes placing a substrate having rows and columns of pixels through on a stage, ejecting organic light-emitting ink to the pixels through on the substrate by using a print head placed above the stage, and sequentially covering pixels through coated with the organic light-emitting ink with a cover plate placed above the stage.
