Provided is a display device including: a substrate including a display area and a peripheral area that includes a bending area disposed adjacent to the display area; a plurality of pixels arranged in the display area; a driving circuit arranged in the peripheral area; a barrier rib layer arranged in the bending area; an input detection layer disposed on the plurality of pixels; and an optical functional layer including a first layer that is disposed on the input detection layer and includes a first opening in an area corresponding to the plurality of pixels, and a second layer that is disposed on the first layer and having a refractive index different from the first layer, wherein the first layer includes at least one valley located between the bending area and the driving circuit.

Display device

A display apparatus includes a substrate including a display area and a peripheral area adjacent to the display area, and including a bending area where at least a portion of the peripheral area is bent, a display element on the display area, a pad portion arranged on the peripheral area with the bending area between the display element and the pad portion, an input sensing layer over the display element, and an optical functional layer over the input sensing layer and including a first layer having an opening corresponding to the display element, and a second layer having a different refractive index from the first layer, and the second layer is arranged to extend to the peripheral area and cover the bending area.

Display apparatus

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.

Display apparatus including multi-layered optical function layer

A display device may include a pixel electrode, a pixel defining layer on the pixel electrode and having a pixel opening that exposes at least a portion of the pixel electrode, an emission layer on the pixel electrode in the pixel opening, an opposite electrode on the emission layer, a first refractive layer on the opposite electrode and having a refractive opening, the first refractive layer having a first refractive index, and a second refractive layer on the first refractive layer and having a second refractive index greater than the first refractive index. A maximum inclination angle of a sidewall of the first refractive layer exposed by the refractive opening with respect to a lower surface of the first refractive layer may be between about 65 degrees and about 90 degrees.
