Abstract: An electroluminescent display device according to an example embodiment of the present disclosure may include a substrate including an active area having an emission area and a non-active area, a planarization layer disposed on the substrate, a light emitting element disposed on the planarization layer, a buffer layer disposed on the light emitting element and having a plurality of holes in a surface thereof and a hydrogen trap layer disposed on the buffer layer. As a result, by preventing hydrogen inflow into an oxide thin film transistor, characteristics and reliability of the thin film transistor can be improved.
