Organic light emitting display device

An organic light emitting display device comprising:

• a substrate having a display area in which a plurality of pixels are disposed, a non-display area outside of the display area, and at least one open hole area defined between the plurality of pixels;
• and
• a stacked layer structure disposed on the substrate and defining the plurality of pixels in the display area, the stacked layer structure including at least one organic layer,
• wherein the at least one open hole area comprises:
• at least one open hole penetrating through the substrate;
• and
• a blocking pattern disposed along a circumference of the at least one open hole to block an introduction path of moisture and oxygen and a propagation path of cracks from spreading to the plurality of pixels adjacent to the at least one open hole by way of the at least one organic layer which extends to the at least one open hole, and
• wherein the blocking pattern separates the at least one organic layer from a corresponding layer that extends to the at least one open hole.
