Abstract

Provided are an organic light-emitting display (OLED) device and a method of manufacturing the same. An OLED device includes: a substrate, a display area on the substrate, the display area including: a first pixel including a first organic light-emitting layer configured to emit first-colored light, a second pixel including a second organic light-emitting layer configured to emit second-colored light, and a third pixel including a third organic light-emitting layer configured to emit third-colored light, and an inspection pattern area in a non-display area on the substrate, the inspection pattern area including a first inspection pixel including a first inspection organic light-emitting layer including a same material as that of the first organic light-emitting layer.

Claims (39)

1. An organic light-emitting display (OLED) device, comprising:

a substrate;

a display area on the substrate, the display area comprising:

a first pixel comprising a first organic light-emitting layer configured to emit first-colored light;

a second pixel comprising a second organic light-emitting layer configured to emit second-colored light; and

a third pixel comprising a third organic light-emitting layer configured to emit third-colored light; and

an inspection pattern area in a non-display area on the substrate, the inspection pattern area comprising:

a first inspection pixel comprising a first inspection organic light-emitting layer comprising a same material as that of the first organic light-emitting layer;

a second inspection pixel;

a first inspection key between the first pixel and the first inspection pixel; and

a second inspection key parallel to the first and second inspection pixels.

2. The OLED device of claim 1 , wherein the second inspection pixel comprises a first inspection hole transporting layer comprising a same material as that of a first hole transporting layer in the first pixel.

3. The OLED device of claim 1 , wherein:

the first inspection key extends in a first direction; and

the second inspection key extends in a second direction crossing the first direction.

4. The OLED device of claim 1 , wherein the first pixel further comprises:

a first electrode below the first organic light-emitting layer, the first electrode comprising a same material as those of the first and second inspection keys; and

a second electrode on the first organic light-emitting layer.

5. The OLED device of claim 4 , wherein the second electrode is on the first inspection organic light-emitting layer and the first inspection hole transporting layer.

6. The OLED device of claim 1 , wherein the inspection pattern area further comprises:

a third inspection pixel comprising a second inspection organic light-emitting layer comprising a same material as that of the second organic light-emitting layer;

a fourth inspection pixel comprising a second inspection hole transporting layer comprising a same material as that of a second hole transporting layer in the second pixel; and

a fifth inspection pixel comprising a third inspection organic light-emitting layer comprising a same material as that of the third organic light-emitting layer.

7. The OLED device of claim 6 , wherein the inspection pattern area further comprises:

a third inspection key between the first pixel and the second inspection pixel;

a fourth inspection key between the second pixel and the third inspection pixel;

a fifth inspection key between the second pixel and the fourth inspection pixel; and

a sixth inspection key between the third pixel and the fifth inspection pixel.

8. The OLED device of claim 1 , further comprising:

a dam configured to surround the display area in the non-display area,

wherein the inspection pattern area is between the display area and the dam.

9. The OLED device of claim 1 , further comprising:

a pad area in the non-display area, the pad area comprising a plurality of pads; and

data link lines in the non-display area, the data link lines connecting the plurality of pads with data lines of the display area,

wherein the inspection pattern area overlaps the data link lines.

10. The OLED device of claim 1 , further comprising:

a gate driver in the non-display area; and

gate lines connected to the gate driver,

wherein the inspection pattern area overlaps the gate lines.
