Claim:
1. A display device comprising: a first transistor comprising: a second transistor comprising: a third insulating layer over the first source electrode, the first drain electrode, the second source electrode, and the second drain electrode; a first electrode over the third insulating layer and electrically connected to the first source electrode or the first drain electrode; an electroluminescent layer on and in contact with the first electrode; and a conductive layer over the third insulating layer and comprising a region overlapping the second gate electrode, wherein the second insulating layer comprises: wherein the first source electrode or the first drain electrode is electrically connected to the first oxide semiconductor layer between the first region and the second region of the second insulating layer, and wherein the second source electrode or the second drain electrode is electrically connected to the second oxide semiconductor layer between the third region and the fourth region of the second insulating layer.
