Abstract:
1. A display device comprising: a first transistor, a second transistor, and a third transistor; a first insulating layer over the first transistor, the second transistor and the third transistor; a first line electrically connected to the first transistor; a second line electrically connected to the second transistor; a third line electrically connected to the third transistor; a pixel electrode over the first insulating layer; a second insulating layer covering and in direct contact with an end portion of the third line and an end portion of the pixel electrode; an EL layer over the pixel electrode and the second insulating layer; and a cathode over the EL layer and the second insulating layer, wherein an EL element comprises the pixel electrode, the EL layer, and the cathode, wherein at least a part of the third line overlaps at least a part of the first line, wherein at least a part of the third line is in parallel with at least a part of the first line, wherein at least a part of the third line is in parallel with at least a part of the second line, wherein the pixel electrode is in direct contact with the first insulating layer, wherein the third line is over and in direct contact with the first insulating layer, wherein the EL element, the first transistor and the third transistor are electrically connected in series with each other, and wherein at least a part of the EL layer is over the first line and the third line.
