    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.
