Classification: CPC H | IPC H

Claim 8:
9. A display apparatus comprising:
a substrate;
a plurality of thin-film transistors and a capacitor disposed on the substrate; and
a display element electrically connected to one of the plurality of thin-film transistors,
wherein a first thin-film transistor of the plurality of thin-film transistors comprises a semiconductor layer, wherein the semiconductor layer comprises a first conductive region, a second conductive region and a first semiconductor region between the first conductive region and the second conductive region, and a lower electrode disposed on the semiconductor layer and at least partially overlapping the first semiconductor region,
the capacitor comprises the lower electrode and an upper electrode disposed on the lower electrode and at least partially overlapping the first semiconductor region,
a first width of the first semiconductor region in a first direction is greater than a second width of the lower electrode in the first direction,
in a plan view, a first boundary between the first semiconductor region and the first conductive region coincides with an edge of the upper electrode,
in the plan view, a second boundary between the first semiconductor region and the second conductive region coincides with an edge of the lower electrode or an edge of the upper electrode,
wherein the first semiconductor region comprises a first channel region overlapping the lower electrode, and a second channel region that does not overlap the lower electrode but overlaps the upper electrode,
wherein the semiconductor layer comprises a non-crystallization region including at least part of the second channel region, and
wherein the semiconductor layer further comprises a crystallization region including the second conductive region.
