Abstract: A display device includes a display panel, a wavelength control layer disposed on the display panel, a light control member disposed on the wavelength control layer, and a cover layer disposed on the light control member. The light control member includes an inorganic layer disposed on the wavelength control layer and having a first refractive index, a first light control layer disposed on the inorganic layer and having a second refractive index, a second light control layer disposed on the first light control layer and having a third refractive index, and a color filter layer disposed on the second light control layer. The first refractive index is greater than the second refractive index and is less than a refractive index of the wavelength control layer, and the third refractive index is greater than the second refractive index and is less than a refractive index of the color filter layer.
