Abstract
An organic light-emitting display device comprises: a lower substrate; an upper substrate facing the lower substrate; and a spacer formed in a sealed space between the lower substrate and the upper substrate and dividing the space into two or more sections; wherein air holes are formed in the spacer and allow air to flow between the sections of the space.

An organic light-emitting display device, comprising:
- a lower substrate;
- an upper substrate facing the lower substrate;
- and
- a spacer formed in a sealed space between the lower substrate and the upper substrate for dividing the sealed space into at least two sections;
- wherein air holes are formed in the spacer and allow air to flow between the sections of the sealed space.
An organic light-emitting display device, comprising:
- a lower substrate;
- a thin-film transistor formed on a surface of the lower substrate;
- a pixel portion defined by a pixel defining layer, and having an organic layer which emits light when receiving a driving voltage from the thin-film transistor;
- a spacer formed on the pixel defining layer in a shape of a line;
- and
- an upper substrate closely attached to the spacer, and facing the lower substrate with a predetermined gap therebetween;
- wherein air holes are formed in the spacer and allow air to flow through the spacer.
A method of manufacturing an organic light-emitting display device, the method comprising the steps of:
- forming a thin-film transistor on a surface of a lower substrate;
- forming a pixel defining layer on the thin-film transistor;
- forming a pixel portion by etching the pixel defining layer;
- forming a spacer on the pixel defining layer;
- forming recessed grooves in the spacer in a direction perpendicular to a lengthwise direction of the spacer;
- and
- providing an upper substrate on the spacer.
A method of manufacturing an organic light-emitting display device, the method comprising the steps of:
- forming a spacer on a lower substrate;
- forming recessed grooves in the spacer in a direction perpendicular to a lengthwise direction of the spacer;
- providing an upper substrate on the spacer;
- attaching a polarizing film to a surface of the upper substrate;
- and
- applying pressure to the upper substrate using a roller.
