Abstract: A display device includes: a substrate; a display element on the substrate; a capping layer on the display element; an optical layer on the capping layer, and including: a first optical layer on the display element; and a second optical layer on the first optical layer; and a thin film encapsulation layer on the optical layer, and including: a first inorganic encapsulation layer on the second optical layer; an auxiliary layer on the first inorganic encapsulation layer; an organic encapsulation layer on the auxiliary layer; and a second inorganic encapsulation layer on the organic encapsulation layer. A refractive index of the second optical layer is smaller than a refractive index of the capping layer, and a refractive index of the first optical layer is between the refractive index of the second optical layer and the refractive index of the capping layer.

Abstract: A light control panel includes: a first substrate; a light control layer that includes first light blocking parts and second light blocking parts that are disposed on the first substrate, extend along a first direction, and are spaced apart from each other along a second direction that crosses the first direction; and a second substrate disposed on the light control layer. The first light blocking parts and the second light blocking part are alternately arranged along the second direction. A first width of each of the first light blocking parts in the second direction and a second width of each of the second light blocking parts in the second direction differ from each other.
