A display device includes a light emitting element layer and a light scattering layer disposed on the light emitting element layer. The light scattering layer may include a low refractive part that includes a plurality of protruding portions and a high refractive part that covers the protruding portions.

Display device and manufacturing method thereof

When a decrease in low-grey level region (e.g., 0 to 80 grey) efficiencies of organic light emitting devices is not constant, deviation among display panels may cause color change and stain in the low luminance region. Aspects of the present disclosure are directed toward a compound to overcome this problem and an organic light-emitting device including the same. The compound may be represented by Formula 1:  Organic light-emitting devices including this compound in the buffer layer were found to have improved efficiencies at low grey levels.
