    Abstract: A display device includes a substrate including pixels, a pixel defining film on the substrate and defining an emission area, an emission layer in the emission area, a first refraction film on the pixel defining film and the emission layer and having a first refractive index, and a second refraction film covering the first refraction film and having a second refractive index. The second refraction film includes a convex surface convexly protruding from a reference surface and overlapping the emission area. Each of the emission area and the convex surface includes first and second edges. The edges of the convex surface are positioned outside the edges of the emission area, and a first interval between the first edges of the convex surface and the emission area is greater than a second interval between the second edges of the convex surface and the emission area.

    Abstract: A display device includes a display panel including a display surface having a Lambertian light emission distribution, and a viewing angle modulator disposed on the display panel. The viewing angle modulator includes a first refractive layer including a diffraction structure on a surface, a refractive index conversion layer disposed on the first refractive layer and including an electro-optical material having a refractive index that changes when a voltage is applied to the electro-optical material, and a second refractive layer disposed on the refractive index conversion layer. The refractive index conversion layer includes a base layer, and an optical structure disposed on the base layer that changes a path of light incident on a surface facing the second refractive layer.
