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.
