Abstract: A display panel in which pixels each include light-emitting parts are two-dimensionally arranged across a main surface of a substrate. The light-emitting parts each include: a first electrode that is light-reflective; a first functional layer disposed above the first electrode; a light-emitting layer disposed above the first functional layer; a second functional layer disposed above the light-emitting layer and including ytterbium; and a second electrode disposed above the second functional layer and being light-transmissive. At least one of the light-emitting layer and the first functional layer is an applied film. With respect to each pixel, at least one of the light-emitting parts differs from any other of the light-emitting parts in terms of light emission color, and the at least one light-emitting part differs from the any other of the light-emitting parts in terms of film thickness of at least one of the light-emitting layer and the first functional layer.

Abstract: A method for manufacturing an organic semiconductor element including applying an organic semiconductor solution to a base is provided. The method includes, before the applying, bringing a pressure of an inert gas close to an ambient pressure while varying the pressure of the inert gas between a negative pressure and a positive pressure with respect to the ambient pressure. The inert gas is contained in a sealed container together with the organic semiconductor solution. The ambient pressure is a pressure of surroundings of the organic semiconductor solution in the applying.

Abstract: Disclosed herein is an organic EL element including a first electrode, a light emitting layer, a ground layer, and a light-transmitting second electrode stacked in this order over a substrate. The ground layer is light-emitting and electrically conductive, and its surface on which the second electrode is stacked has a surface roughness of 0.3 to 2.7 nm. The second electrode is a silver thin film layer formed of silver or containing silver as a main constituent.
