Organic light-emitting display device and method of manufacturing the same

摘要

The organic light-emitting display device includes: a substrate including a transistor region; and a thin-film transistor formed over the transistor region of the substrate and having a planarization film which is disposed over a source/drain electrode and a pixel defining layer which includes an aperture exposing a portion of a first electrode electrically connected to the source/drain electrode and defining a pixel region, wherein an outgassing hole is formed in a region of the pixel defining layer other than the aperture to expose the planarization film.

1. A method of manufacturing an organic light-emitting display device, the method comprising: forming a planarization film over a transistor region of a substrate;
forming a first electrode, which is electrically connected to a source/drain electrode, over the planarization film; providing a pixel defining layer which comprises an aperture exposing a portion of the first electrode to define a pixel region; forming at least two outgassing holes in a region of the pixel defining layer other than the aperture to expose the planarization film; and forming an organic light-emitting layer over the first electrode of the pixel region by using a nozzle printing process such that the nozzle-printing process does not release the organic material into the at least two outgassing holes, wherein outgassing generated by the planarization film during forming of the organic light-emitting layer is released from the planarization film through the at least two outgassing holes, wherein the at least two outgassing holes are only formed adjacent to a first edge and a second edge of the pixel region, wherein the first edge and the second edge face each other, wherein the first edge and the second edge face each other.
