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

Claim 0:
1. A thin-film transistor array substrate comprising:
a substrate;
a thin-film transistor disposed on the substrate, wherein the thin-film transistor includes a semiconductor layer including a channel area, and a gate electrode overlapping the channel area; and
a storage capacitor including a lower electrode disposed on the channel area, 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 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.
