Abstract: An optical film, a display device including the same, and a method of manufacturing the optical film, the film including a first refractive index layer including a plurality of protrusions; a second refractive index layer covering the plurality of protrusions, the second refractive index layer having a refractive index that is different from a refractive index of the first refractive index layer; and a support layer on the first refractive index layer or the second refractive index layer, wherein a ratio of a height to a width of the protrusion is 0.5 or more.

Abstract: A display device is provided. The display device includes a display panel including a folding region, first and second non-folding regions at opposite sides of the folding region; a first support plate below the display panel to overlap the first non-folding region and to partially overlap the folding region; a second support plate below the display panel to overlap the second non-folding region and to partially overlap the folding region; a first plate coupling film between the display panel and the first support plate to overlap the first non-folding region; a second plate coupling film between the display panel and the second support plate to overlap the second non-folding region; a first step compensating member between the display panel and the first support plate to overlap the folding region, apart from the first plate coupling film, and including a light shielding layer; and a second step compensating member between the display panel and the second support plate to overlap the folding region, apart from the second plate coupling film, and including a light shielding layer.
