Abstract: Disclosed is an electroluminescence display device. The electroluminescence display device includes a flexible substrate, a first metal layer, an inorganic material layer, a recessed portion, a second metal layer, and an organic material layer. The flexible substrate has a bending axis. The first metal layer is disposed on the flexible substrate to be parallel with the bending axis. The inorganic material layer is stacked on the first metal layer. The recessed portion is disposed in the inorganic material layer to be parallel to the bending axis and exposes the first metal layer. The second metal layer extends in parallel to the bending axis, covers the recessed portion, and is in contact with the first metal layer. The organic material layer covers the inorganic material layer and the second metal layer.
