Abstract: A display device can include a substrate including a display area, a subpixel positioned on the substrate and positioned in the display area, and a black bank positioned on the substrate. The black bank can include a first opening corresponding to an emission area of the subpixel, and quantum dots that absorb light having a wavelength in a visible light region. As a result, the display device can reduce external light reflectance.

Abstract: Provided are a light extraction sheet for a display device and a manufacturing method thereof. The light extraction sheet is disposed on an emission area of the display device. The light extraction sheet includes a base layer formed of an insulating material. Transparent metal oxide crystals are formed on one or both surfaces of the base layer as a pattern of irregular curves. Total reflection occurring at the boundary of an emission layer is overcome, and light extraction efficiency is improved.
