Patent ID: 11881487
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A display device comprising:
a substrate;
a plurality of signal lines including an initialization voltage line, a plurality of scan lines, a control line, a storage line, a data line, and a driving voltage line disposed on the substrate;
a first electrode;
an emission layer disposed on the first electrode;
a second electrode disposed on the emission layer; and
a plurality of transistors connected to the plurality of signal lines, and including:
a first transistor connected to a first scan line from among the plurality of scan lines, the storage line, and the first electrode, and including:
a semiconductor layer disposed on the substrate, and including:
a first channel portion;
a second channel portion;
a connecting portion disposed between the first channel portion and the second channel portion, and
a plurality of electrode regions;

a first insulating layer disposed on the semiconductor layer; and
a gate conductor disposed on the first insulating layer, and including a first gate electrode overlapping the first channel portion and a second gate electrode overlapping the second channel portion,

wherein
the first channel portion and the second channel portion of the semiconductor layer each have a first width in directions respectively perpendicular to main extension directions of the respective first and second channel portions, and
the first width is greater than a second width of the connecting portion extending directly from the respective first and second channel portions in a direction perpendicular to a main extension direction of the connecting portion being the same as the respective main extension directions of the respective first and second channel portions.
