Classification: CPC H  G | IPC G  H

Claim 1:
2. The display substrate according to claim 1, 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;
the first insulating layer further has a second via hole;
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 and a dummy portion that are electrically insulated from each other, and the dummy portion is closer to the first light-transmitting hole than the active layer connection portion;
the active layer connection portion is coupled with an active layer of the second thin film transistor; and
the conductive light-shielding pattern is coupled with the dummy portion through the second via hole.
