Abstract: An organic electroluminescence (EL) display panel includes a substrate; first electrodes spaced away from each other and arrayed in rows and columns above the substrate; light-emitting layers including organic light-emitting material and disposed above the first electrodes; a second electrode disposed above the light-emitting layers; a first protection layer including resin and disposed above the second electrode but not within an auxiliary region which, in plan view, extends in a column direction between ones of the first electrodes that are adjacent in a row direction across the substrate; a second protection layer including inorganic material and disposed above the first protection layer and the second electrode; and an auxiliary electrode layer extending in the column direction within the auxiliary region and electrically connecting to the second electrode through a contact opening in the first protection layer within the auxiliary region.

Abstract: An organic electro-luminescence (EL) element includes a first electrode, a light emitting layer, and a second electrode layered in this order above a substrate. At least one of the first electrode and the second electrode is a light transmissive electrode. The light transmissive electrode includes a base metal layer and a silver thin film. The base metal layer is a metal layer including an alkali metal or an alkaline earth metal as a material. The silver thin film is silver or a silver alloy including silver as a main component, and is disposed on and in contact with the base metal layer.

Abstract: An organic EL display panel including: a substrate; pixel electrodes that are arrayed in a matrix above the substrate; first organic functional layers that are on or above the pixel electrodes in one-to-one correspondence with the pixel electrodes, the first organic functional layers spaced apart from one another; a second organic functional layer that continuously covers the first organic functional layers; and a counter electrode that opposes the pixel electrodes and covers the second organic functional layer. In the organic EL display panel, the first organic functional layers each include a hole injection layer, and the second organic functional layer has greater electric resistance than each of the first organic functional layers and has a portion extending into an absence region, the absence region being a space between adjacent ones of the first organic functional layers.
