Abstract: A display device may include a first electrode, a second electrode, an emission layer, an intervening layer, and a first encapsulation layer. The second electrode may overlap the first electrode. The emission layer may be disposed between the first electrode and the second electrode, may overlap the first electrode, and may include a light emitting material. The intervening layer may directly contact the second electrode, may be spaced from each of the first electrode and the emission layer, and may include a fluorine compound. A first section of the first encapsulation layer may overlap the emission layer. The intervening layer may be positioned between the second electrode and a second section of the first encapsulation layer.
