  • Publication number: 20250081723
    Abstract: An organic EL element includes a pixel electrode, a light emitting function layer that is formed on the pixel electrode, an electron injection layer formed on the light emitting function layer, and a counter electrode that is formed on the electron injection layer and that has semi-transmissive reflectivity, in which the counter electrode contains a reductive material that reduces material of the electron injection layer and Ag with atomic ratio of 75% or more, and an adsorption layer is formed on the counter electrode.

  • Publication number: 20240386851
    Abstract: An electroluminescent device includes a scanning line that extends in a first direction, a light emitting element, a driving transistor that supplies a driving current to the light emitting element, a first conductive layer that is supplied a fixed potential and extends in the first direction, a second conductive layer that is supplied the fixed potential and is disposed on a different layer than the first conductive layer, and a third conductive layer that is electrically connected to a first terminal of the driving transistor and to the light emitting element, and is disposed on a same layer as the second conductive layer. The third conductive layer is surrounded by the second conductive layer in plan view.
