Abstract
An organic electroluminescence display apparatus includes an insulating layer including a concave portion having a concave first upper surface, a first electrode including a curved electrode portion having a concave second upper surface overlapped with the concave portion, a pixel definition layer including a first opening defined therethrough to expose the second upper surface, an organic layer disposed on the first electrode, a second electrode disposed on the organic layer, and a light blocking layer including a second opening defined therethrough. The second opening has a width smaller than the first opening and overlaps with the first opening.
