Abstract
A method for fabricating an organic light emitting display device includes forming a first electrode on a substrate; forming a pixel-defining film having an opening exposing the first electrode; forming an ink non-reactive solvent portion by discharging of an ink non-reactive solvent at the opening and forming an organic light emitting layer by discharging an organic light emitting ink on the ink non-reactive solvent portion; and forming a second electrode on the organic light emitting layer.
Claims5
An inkjet print device comprising:
- an ink non-reactive solvent discharge mechanism comprising a first nozzle and being configured to form an ink non-reactive solvent portion by discharging ink non-reactive ink in an opening of a pixel-defining film and on a first electrode, the opening exposing the first electrode on a substrate of an organic light emitting display device;
- and
- an organic light emitting ink discharge mechanism comprising a second nozzle and being configured to form an organic light emitting layer by discharging an organic light emitting ink on the ink non-reactive solvent portion,
- wherein the ink non-reactive solvent discharge mechanism and the organic light emitting ink discharge mechanism are configured to move in a first direction,
- wherein the first nozzle and the second nozzle are coupled to one moving device and are adjacent to each other in the first direction, and
- wherein a distance between the first nozzle and the second nozzle is equal to a width of a pixel, the width of the pixel being equal to a distance between adjacent openings of the pixel-defining film.
