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.
