    摘要: An electroluminescent device includes a light-emitting element, a drive transistor that supplies a driving current corresponding to a gradation voltage to the light-emitting element, a first conductive layer that is electrically connected to a gate of the drive transistor, and a second conductive layer that is supplied a fixed potential and that is disposed on a same layer as the first conductive layer. The first conductive layer and the second conductive layer are disposed apart and electrically insulated from one another, and in plan view, the first conductive layer is surrounded by the second conductive layer.

    摘要: A first light-emitting element and a second light-emitting element that have a resonance structure that causes output light from a light-emission functional layer to resonate between a reflective layer and a semi-transmissive reflective layer, and a pixel definition layer, and in which an aperture part is formed to correspond to each of the first light-emitting element and the second light-emitting element, are formed on a base. A first interval between the reflective layer and the semi-transmissive reflective layer in the first light-emitting element and a second interval between the reflective layer and the semi-transmissive reflective layer in the second light-emitting element are different, and a film thickness of the pixel definition layer is less than a difference between the first interval and the second interval.
