Abstract: A display device includes a base substrate, a plurality of display elements, a first light control layer, and a second light control layer. The base substrate includes a pixel region and a peripheral region adjacent to the pixel region. The display elements are disposed on the base substrate, overlap the pixel region in a plan view, and are configured to generate a first light. The first light control layer is disposed on the display elements, and includes a transmission part configured to transmit the first light, a first light conversion part configured to convert the first light into a second light, and a second light conversion part configured to convert the first light into a third light. The second light control layer overlaps at least a portion of the first light conversion part in the plan view and is configured to convert the first light into the second light.

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.

Abstract: A liquid crystal display panel including a first display substrate, a second display substrate coupled to and spaced apart from the first display substrate, and a liquid crystal layer disposed between the first and second display substrates. The first and second display substrates include inorganic layers containing an inorganic silicon-based material. The liquid crystal layer includes alignment molecules vertically aligned with respect to the inorganic layers, and liquid crystal molecules vertically aligned between the inorganic layers. A manufacturing method of the liquid crystal display panel includes surface-treating the inorganic layers to vertically align the liquid crystal molecules.
