Abstract:
1. A light emitting device comprising: a transistor; a first insulating film over the transistor; a conductive layer over the first insulating film; a second insulating film over the first insulating film; an electrode over the conductive layer; a third insulating film over the electrode; and a layer comprising an organic compound over the electrode, wherein the conductive layer is electrically connected to one of a source and a drain of the transistor via a contact hole of the first insulating film, wherein the second insulating film is in direct contact with an edge portion of the conductive layer, wherein the third insulating film comprises an opening portion, wherein a part of the layer is formed inside the opening portion, wherein the conductive layer comprises a first concave portion, wherein the electrode comprises a second concave portion, wherein the first concave portion overlaps with the contact hole of the first insulating film, wherein the second concave portion partly overlaps with the first concave portion, wherein the second concave portion is in direct contact with the first concave portion, wherein the third insulating film overlaps with the first concave portion and the second concave portion, wherein the transistor comprises a plurality of gate electrodes, and wherein the electrode is in direct contact with a side surface and a top surface of the second insulating film.
