Abstract: An organic EL display panel including: a substrate; a first lower electrode and a second lower electrode disposed over the substrate with a gap therebetween in a first direction; a wall separating a space above the first lower electrode and a space above the second lower electrode from one another; organic light-emitting layers respectively disposed in the spaces; and an upper electrode extending over the organic light-emitting layers. The wall includes a first portion disposed over the gap and two second portions each of which is disposed over a different one of the first lower electrode and the second lower electrode. The first portion is between the two second portions in the first direction, and at least a part of a bottom face of the first portion is positioned higher than a bottom face of the second portion.

Abstract: Light emitters are two-dimensionally disposed along a main surface of the substrate. The light emitters each include: a first electrode; an organic light-emitting layer; an intermediate layer; a charge transport layer; and a second electrode. Such layers are disposed in the stated order with the first electrode closest to the substrate. The intermediate layer contains a fluoride of an alkali metal or a fluoride of an alkaline earth metal. The charge transport layer contains an organic material doped with an alkali metal or an alkaline earth metal. The light emitters are partitioned from one another by first banks extending in one direction along the main surface of the substrate and second banks extending in a direction intersecting the one direction. Surface portions of the first banks facing the light emitters have greater liquid repellency than surface portions of the second banks facing the light emitters.

Abstract: A organic EL display panel includes an inter-layer insulation film, a pixel electrode, auxiliary wiring, a partition layer, an organic light-emitting layer, and a common electrode. The inter-layer insulation film has at least one paired concave portion and non-concave portion disposed in a region over the auxiliary wiring, a top face of the concave portion being concave with respect to a top face of the non-concave portion, and the auxiliary wiring includes a part over the concave portion and a part over the non-concave portion, a top face of the part over the concave portion being concave with respect to a top face of the part over the non-concave portion.
