Display apparatus and method of manufacturing the same

A display apparatus comprising:

• a substrate comprising a display area and a peripheral area outside the display area;
• a display element arranged on the substrate in the display area;
• an encapsulation layer arranged on the display element;
• a first insulating layer arranged on the encapsulation layer and comprising a first opening that corresponds to a light-emitting area of the display element;
• and
• a second insulating layer covering the first insulating layer,
• wherein a second refractive index of the second insulating layer is greater than a first refractive index of the first insulating layer, and
• wherein the display apparatus further comprises a protruding dam that protrudes from the first insulating layer in the peripheral area.

A method of manufacturing a display apparatus, the method comprising:

• forming a display element in a display area of a substrate, wherein the substrate comprises the display area and a peripheral area outside the display area;
• forming an encapsulation layer that covers the display element;
• forming a first insulating layer on the encapsulation layer, wherein the first insulating layer comprises a first opening corresponding to a light-emitting area of the display element;
• and
• forming a second insulating layer covering the first insulating layer,
• wherein a second refractive index of the is second insulating layer is greater than a first refractive index of the first insulating layer.
