    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 curved display device includes a display substrate, an opposite substrate, and a liquid crystal layer interposed between the display substrate and the opposite substrate. The display substrate is curved along a first direction and includes a pixel electrode and a second alignment layer disposed on the pixel electrode. The opposite substrate is coupled to the display substrate to be curved along the first direction and includes a common electrode and a first alignment layer disposed on the common electrode. The first alignment layer comprises different material from the second alignment layer. The pixel electrode includes branch portions extending in a direction inclined with respect to the first direction when viewed in a plan view, and a pitch, which is defined by a sum of a width of each branch portion and a distance between the branch portions, is within a range from about 7.5 micrometers to about 8.5 micrometers.
