Abstract
A display device includes a light-emitting element, a thin film encapsulation layer disposed on the light-emitting element, a protection layer disposed on the thin film encapsulation layer, a first sensing electrode disposed on the protection layer, an insulating layer disposed on the first sensing electrode, and a second sensing electrode disposed on the insulating layer, in which at least one of the thin film encapsulation layer and the insulating layer has a multi-layer structure including first and second alternating layers forming at least three layers, and the first layer includes a first material having a first refractive index and the second layer includes a second material having a second refractive index different from the first refractive index.
