Classification: CPC H | IPC H

Claim 0:
1. A display device, comprising:
a substrate; and
a plurality of pixels each including a transistor and an electroluminescence element on the substrate,
wherein the transistor comprising:
a first gate electrode on the substrate;
a second gate electrode overlapping at least one portion of the first gate electrode;
an oxide semiconductor layer between the first gate electrode and the second gate electrode;
a first insulating layer between the first gate electrode and the oxide semiconductor layer; and
a second insulating layer between the oxide semiconductor layer and the first gate electrode,

wherein the electroluminescence element comprising:
a first electrode;
a second electrode opposite to the first electrode;
a light emitting layer between the first electrode and the second electrode; and
an electron transfer layer between the light emitting layer and the first electrode,

wherein the oxide semiconductor layer comprising:
a channel region overlapping the first gate electrode and the second gate electrode;
a first low-resistance region and a second low-resistance region adjacent said channel region; and

wherein an edge of the first low-resistance region and an edge of the second low-resistance region overlap an edge of the first gate electrode,
wherein the oxide semiconductor layer extends into a region overlapping the electroluminescence element,
wherein the first electrode comprises same layer as the oxide semiconductor layer, and the first low-resistance region and the first electrode are continuous.
