Patent ID: 11916083
Assignee: BOE TECHNOLOGY GROUP CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 13:
14. The display substrate according to claim 8, wherein one of a source electrode and a drain electrode, proximate to the first light-transmitting hole, of the second thin film transistor includes:
an active layer connection portion coupled with an active layer of the second thin film transistor; and
a dummy portion closer to the first light-transmitting hole than the active layer connection portion, the dummy portion and the active layer connection portion being electrically insulated from each other, wherein
the conductive light-shielding pattern is coupled with one of the source electrode and the drain electrode, proximate to the first light-transmitting hole, of the first thin film transistor through the first via hole, and is further coupled with the dummy portion through the second via hole, and
the conductive electrode is coupled with the conductive light-shielding pattern through the fourth via hole.
