Abstract: A display device includes: a display panel; an input sensing unit including a sensing insulation layer and a conductive layer, which overlaps the non-emissive region; a light control layer disposed on the input sensing unit; and a window disposed on the light control layer. The light control layer includes: a high refractive index pattern, which covers each of a plurality of emissive regions in a plan view and has a first refractive index; and a low refractive index layer, which covers the high refractive index pattern and the conductive layer, and has a second refractive index smaller than the first refractive index. A separation distance by which one side surface of the high refractive index pattern is spaced apart from one side surface of an emissive region closest to the one side surface of the high refractive index pattern among the emissive regions ranges from 6 μm to 9 μm.
