Abstract: An electroluminescent display is disclosed. The electroluminescent display includes a display panel including sub-pixels in which a light emitting area is defined and wirings connected to the sub-pixels. The sub-pixels have a transistor and a light emitting element. The wirings include a first wiring arranged along a first axis direction or a second axis direction perpendicular to the first axis direction. The first wiring is disposed under a first electrode of the light emitting element with an organic insulating layer interposed therebetween, and includes an overlapping portion overlapping with the light emitting area when viewed from plan. The overlapping portion of the first wiring has a shape with symmetry with respect to a center of gravity of the light emitting area.
