An electroluminescence display device including a thin film transistor layer formed on a substrate, at least one insulating layer, and a pixel layer that includes a first electrode layer, a second electrode layer, and an intermediate layer interposed between the first electrode layer and the second electrode layer and having at least an emitting layer. The pixel layer further includes a reflection layer that is disposed under the first electrode layer and that extends to a via hole formed in the insulating layer, and an auxiliary conductive layer is disposed under the reflection layer. The auxiliary conductive layer extends to the via hole, and the first electrode layer contacts at least a portion of the auxiliary conductive layer.
