| Zusammenfassung: | According to an embodiment of the present invention, an electroluminescent display device can comprise: a thin film transistor on a substrate; an organic film on the thin film transistor; a first electrode disposed on the organic film, and connected to the thin film transistor through a contact hole of the organic film; a bank layer disposed on the organic film, and covering at least one side surface of the first electrode; a light emitting structure on the first electrode and the bank layer; a second electrode on the light emitting structure; and a penetration delay film located between the bank layer and the light emitting structure, and having at least one hole. Therefore, an objective of the present invention is to prevent outgas generated from an organic film from penetrating into a light emitting structure in a light emitting region by configuring at least one blocking film made of an inorganic material between the light emitting structure and the organic film of the electroluminescent display device, thereby preventing the reduction of a lifespan of the light emitting display device.
