Assignee: LG DISPLAY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. 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 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 on the first oxide semiconductor pattern, and
a second electrode in contact with the other side of the first oxide semiconductor pattern on 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, and
a second electrode in contact with the other side of the second oxide semiconductor pattern,

wherein the circuit layer includes a first-first metal pattern disposed on the substrate to overlap the first oxide semiconductor pattern, a first-second 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-second metal pattern,
wherein the first and second electrodes of the first transistor do not overlap with the first-second metal pattern from a cross-sectional view,
wherein the second electrode of the first transistor extends toward the substrate and contacts the first-first metal pattern.
