Light-emitting device with an insulating partition

摘要

A low-power light-emitting device which can be manufactured in simple steps and is suitable for increasing definition and the size of a substrate is provided. The light-emitting device includes a layer for blocking visible light; a conductive layer that partly overlaps with the layer for blocking visible light; a color filter layer that includes an opening over the layer for blocking visible light; a first electrode layer for transmitting visible light that is connected to the conductive layer through the opening, over the color filter layer; an insulating partition over the first electrode layer overlapping with the opening; a layer containing an organic compound over the first electrode layer and the partition; and a second electrode layer over the layer containing an organic compound. The layer containing an organic compound includes a layer containing a donor substance and an acceptor substance and a layer containing a light-emitting organic compound.
