Abstract: An organic electroluminescence display apparatus includes: an insulating layer including a flat surface, a first concave surface and a second concave surface extending from one end and another end of the flat surface, respectively; a first electrode on the insulating layer and including a first concave electrode surface overlapping with the first concave surface, a second concave electrode surface overlapping with the second concave surface, and a flat electrode surface overlapping with the flat surface; an organic layer on the first electrode; a second electrode on the organic layer, and a plurality of light shielding members on the second electrode with an opening therebetween, the opening overlapping with the organic layer. One end of each of the light shielding members is closer to the second concave surface than to the first concave surface.
