Abstract

Provided is a display apparatus having improved reliability by effectively controlling spreading of an organic layer. The display apparatus includes a substrate including 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 including 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 on the peripheral area, and that surrounds the second layer.
