Classification: CPC H  G | IPC G  H

Claim 15:
16. A display panel comprising:
a circuit layer disposed on a substrate and including a plurality of transistors;
a light emitting element layer disposed on the circuit layer and including a plurality of light emitting elements; and
an encapsulation layer on the light emitting element layer,
wherein the circuit layer includes at least a first transistor and a second transistor,
wherein the first transistor includes:
a first oxide semiconductor pattern,
a gate electrode overlapping the first oxide semiconductor pattern above the first oxide semiconductor pattern,
a first electrode in contact with one side of the first oxide semiconductor pattern, and
a second electrode in contact with the other side of the first oxide semiconductor pattern, and

wherein the second transistor includes:
a second oxide semiconductor pattern,
a gate electrode overlapping the second oxide semiconductor pattern above the second oxide semiconductor pattern,
a first electrode in contact with one side of the second oxide semiconductor pattern,
a second electrode in contact with the other side of the second oxide semiconductor pattern,

wherein the circuit layer includes a third oxide semiconductor pattern adjacent to and spaced apart from the second oxide semiconductor pattern,
wherein the circuit layer includes a first metal pattern disposed on the substrate to overlap the second oxide semiconductor pattern, and a second metal pattern disposed between the second oxide semiconductor pattern and the first metal pattern, and
wherein the second electrode of the second transistor extends between the second and third oxide semiconductor patterns and contacts the second metal pattern.
