Abstract
An organic luminescence includes pixel electrodes. Banks are each generally between adjacent ones of the pixel electrodes. The banks define apertures that each correspond to one of the pixel electrodes. An organic luminescent layer is within each of the apertures, and an upper electrode is above the banks and the organic luminescent layer. At least a portion of a periphery of each of the apertures includes curved portions and cusps. The curved portions are concave, and adjacent ones of the curved portions define each of the cusps.
