## 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

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 4)

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.

### Claim 6 (depends on 1)

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.

### Claim 7 (depends on 6)

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.

### Claim 8 (depends on 1)

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.

### Claim 9 (depends on 1)

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.

### Claim 10 (depends on 1)

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.
