Abstract: A display device includes a light emitting element layer, and an optical pattern layer disposed on the light emitting element layer. The optical pattern layer includes a first pattern layer having a base part and protruding parts, and a second pattern layer having a refractive index less than a refractive index of the first pattern layer to scatter light incident to the optical pattern layer and minimize reduction in front efficiency, thereby providing an improved display quality of a side viewing angle.

Abstract: A display apparatus includes a substrate, a display element on the substrate, a low-reflection inorganic layer on the display element, a light blocking layer on the low-reflection inorganic layer and defining an opening corresponding to an emission area of the display element, and a reflection control layer filling the opening of the light blocking layer. The light blocking layer includes a first light blocking layer and a second light blocking layer having different light absorption wavelength spectra from each other.

Abstract: A display apparatus includes a display element on a substrate, a low-reflection layer on the display element, a light blocking layer on the low-reflection layer, the light blocking layer defining an opening corresponding to an emission area of the display element, and the light blocking layer including a body part that absorbs visible light and a light absorbing agent that is disposed in the body part and absorbs light in a wavelength band of about 380 nanometers (nm) to about 500 nm, and a reflection adjustment layer filling the opening of the light blocking layer.
