Abstract
A display device includes a light-emitting element layer and an encapsulation layer disposed on the light-emitting element layer. The encapsulation layer includes a first inorganic film having a first refractive index at a wavelength between about 380 nm and about 500 nm, the first refractive index being between about 1.5 and about 1.7, a second inorganic film disposed on the first inorganic film and having a second refractive index at a wavelength between about 380 nm and about 500 nm, the second refractive index being between about 1.5 and about 1.7, and an organic film disposed between the first inorganic film and the second inorganic film, and having a third refractive index at a wavelength between about 380 nm and about 500 nm, the third refractive index being between about 1.5 and about 1.7. Accordingly, the display device including the encapsulation layer with the high light transmittance may have the high light emission efficiency.
