Patent ID: 11925063
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 11:
12. A display device comprising:
a substrate;
a scan line extending in a first direction on the substrate;
a data line extending in a second direction crossing the first direction;
a pixel circuit electrically connected to the scan line and the data line; and
a display element connected to the pixel circuit,
wherein the pixel circuit includes
a driving thin-film transistor disposed on the substrate, wherein the driving thin-film transistor includes a driving semiconductor layer including a driving channel area, and a driving gate electrode disposed to overlap the driving channel area, and
a storage capacitor including a lower electrode integrally formed with the driving gate electrode as a single unitary unit, and an upper electrode disposed to overlap the lower electrode, wherein an opening having a single closed curve-shape is defined through the upper electrode,
wherein, on a plane, the upper electrode includes a first recessed portion and a second recessed portion, each exposing a side edge defining an outer terminal edge of the lower electrode, while a remaining side edge defining the outer terminal edge of the lower electrode is overlapped by the upper electrode, the outer terminal edge defining a shape of an entirety of the lower electrode in a plan view in a thickness direction of the substrate,

wherein the opening is disposed between the first recessed portion and the second recessed portion.
