摘要： There is provided a method of manufacturing an organic light-emitting device including: forming a first organic material layer on a substrate; and forming a mask in a first region on the first organic material layer, and then selectively removing the first organic material layer to form a first organic layer in the first region.

摘要： 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.
