Abstract
A display device includes: a display area; a display element which emits light and includes a pixel electrode, an opposite electrode, and a light emission layer between the pixel electrode and the opposite electrode; an encapsulation layer covering the display element; sensing electrodes disposed on the encapsulation layer; and a light-shielding layer disposed on each of the sensing electrodes to correspond to each of the sensing electrodes. The encapsulation layer includes: a first organic layer having a refractive index, a first opening defined in the first organic layer and corresponding to the light emission layer of the display element, and a first refractive layer covering the first organic layer.
