Abstract: A display device includes a display panel, an optical layer disposed on the display panel, a window disposed on the optical layer, and a light control layer. The light control layer is disposed between the display panel and the optical layer or between the optical layer and the window. The light control layer includes a plurality of transmission portions spaced apart from each other and a light blocking portion filled between the transmission portions. A thickness of each of the transmission portions and a width of each of the transmission portions in a cross-section are determined by a function of a refractive index of the transmission portions, and an exit angle of light emitted from the display panel and propagating through the light control layer.
