Abstract: An organic EL display panel manufacturing method including: preparing a substrate; forming at least first electrodes on the substrate; forming, by performing photolithography on the substrate having the first electrodes, a bank layer made of a photoresist and having apertures corresponding one-to-one with the first electrodes; forming a functional layer in each of the apertures by applying an ink containing a functional material to the aperture and drying the applied ink; and forming at least a second electrode on the functional layer. The forming of the bank layer includes: applying the photoresist to the substrate having the first electrodes; forming apertures corresponding one-to-one with the first electrodes in the photoresist by performing exposure using a mask and then developing the photoresist; after forming the apertures, performing exposure of the photoresist having the apertures; after performing the exposure of the photoresist having the apertures, baking the photoresist.

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.
