Claim 1:
2. An electronic device comprising:
a display device, the display device comprising:
a protruding portion protruding from part of a short-side of the display device;
a first substrate having flexibility;
an oxide layer over the first substrate;
a first conductive layer and a second conductive layer over the oxide layer;
a first insulating layer over the first conductive layer and the second conductive layer;
a third conductive layer over the first insulating layer and overlapping with the first conductive layer;
a fourth conductive layer over the first insulating layer;
a light-emitting element over the fourth conductive layer;
an adhesive layer over the light-emitting element; and
a second substrate over the adhesive layer,

wherein the third conductive layer is electrically connected to the first conductive layer,
wherein the third conductive layer is configured to function as one of a plurality of first wirings,
wherein the second conductive layer is configured to function as a gate electrode of a first transistor,
wherein the fourth conductive layer is configured to function as one of a source electrode and a drain electrode of the first transistor,
wherein the third conductive layer and the fourth conductive layer are formed from a same layer,
wherein the protruding portion comprises a connection terminal and a bending portion,
wherein the bending portion is bent and the protruding portion is folded back so that a first portion of a first surface of the first substrate faces a second portion of the first surface of the first substrate, whereby a surface of the connection terminal overlaps with a back side of a display portion,
wherein a source driver circuit provided over the protruding portion overlaps with the back side of the display portion,
wherein the display device is incorporated into the electronic device with the bending portion folded back,
wherein, in a short-side direction of the display device, each of two end portions of a short-side of the protruding portion is provided farther inside than end portions of the short-side of the display device, and
wherein the plurality of first wirings has a region comprising an opening and a branching portion where the plurality of first wirings branches into a plurality of second wirings with the opening therebetween.
