EL element, method for forming EL element, and display panel that uses EL element

摘要

An EL element including a first electrode, a luminescent layer, an insulation layer, and a second electrode is laminated so that a short circuit between the first electrode and the second electrode at a defect of the insulation layer between the luminescent layer and the second electrode is prevented. A cavity 41 is formed in the layer 4 under an area 51 at which the second insulation layer 5 is missing. The second electrode 6 is separated by the cavity 41 from the first insulation layer 3 located under the luminescent layer 4 to prevent a short circuit.
