1. A display apparatus comprising:
a substrate comprising a display area, and a peripheral area outside the display area;
a display element at the display area;
an input-sensing layer over the display element; and
an optical functional layer on the input-sensing layer, and comprising a first layer, which corresponds to the display area and the peripheral area, and a second layer on the first layer, and having a greater refractive index than the first layer,
wherein the first layer defines a first valley portion defining first holes that is in the peripheral area, and that surrounds the second layer.
