An electroluminescent display device includes a transparent substrate and an electroluminescent element disposed over the substrate. The electroluminescent element has a first electrode disposed over the substrate, a second electrode disposed over the first electrode and a light emitting layer disposed between the first and second electrodes. The display device also includes a thin film transistor driving the electroluminescent element, and a protection film disposed over the second electrode and being configured to prevent a penetration of moisture into the electroluminescent element. The second electrode is formed by evaporating aluminum so that the light emitting layer receives no damage, and the protection film is deposited by sputtering to provide a film with a high relative density so that moisture is prevented from entering the electroluminescent element.
