The organic electroluminescence display comprises a pixel defining layer provided with an opening, a first electrode formed on the opening of the pixel defining layer in a recessed structure, an organic emission layer formed on the first electrode, and a second electrode. The organic emission layer is formed to be recessed in the first electrode, so that the first electrode surrounds the organic emission layer.
