摘要： In an organic EL display device (electroluminescent device) including an organic EL element (electroluminescent element), a sealing film is provided to seal the organic EL element. The sealing film includes a first inorganic layer, a first organic layer, a second inorganic layer, a second organic layer, and a third inorganic layer (uppermost inorganic layer), which are arranged in this order. The first and second organic layers are formed so that the thickness of the end portions gradually decreases from the thickness of the central portions. The third inorganic layer is provided to cover the end portions of each of the first inorganic layer, the first organic layer, the second inorganic layer, and the second organic layer.

摘要： A display device includes: a first conductive layer on a resin substrate layer; a planarization film on the first conductive layer; and OLEDs on the planarization film. There is provided a second conductive layer in a frame area surrounding a display area. The second conductive layer is in contact with second electrodes of the OLEDs on the planarization film and also in contact with the first conductive layer in an external side of the planarization film. The second electrode is electrically connected to the first conductive layer via the second conductive layer. The planarization film includes, in the frame area, a portion where there is provided a trench. The first conductive layer is exposed from the planarization film in the trench. The second electrode is electrically connected to the first conductive layer via the second conductive layer in the trench.
