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

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.
