Display apparatus having a larger display region and moisture impermeability

A display apparatus comprising:

• a substrate having a first region and a second region surrounding the first region;
• an insulating part disposed above the substrate, covering the first region and the second region, and comprising a first opening portion in the second region;
• a dam part disposed above the insulating part in the second region and surrounding a periphery of the first opening portion;
• a first organic insulating layer disposed above the insulating part and covering an inner surface of the first opening portion;
• an organic light-emitting device disposed above the insulating part in the first region and comprising a pixel electrode;
• an encapsulation layer, disposed above the insulating part in both the first region and the second region, the encapsulation layer covering the organic light-emitting device;
• and
• a first material layer disposed between the substrate and the insulating part, wherein the fist opening portion exposes at least a portion of the first material layer,
• wherein the first organic insulating layer exposes at least a portion of the first material layer.
