Claim 24:
25. The method according to claim 24, further comprising:
forming a first gate metal layer on a side of the semiconductor layer away from the substrate, and performing a patterning process on the first gate metal layer to form a gate electrode of the first switch and a gate electrode of the second switch;
using the gate electrode of the first switch and the gate electrode of the second switch as a mask, doping a portion of the semiconductor layer that is not covered by the gate electrodes so that the portion of the semiconductor layer that is not covered by the gate electrodes is formed as a conductive portion, and a portion of the semiconductor layer covered by the gate electrode is formed as a channel portion;
forming a second gate metal layer on a side of the first gate metal layer away from the semiconductor layer, and performing a patterning process on the second gate metal layer to form a signal output line; the signal output line including a first output line portion extending in the first direction;
forming a first insulating layer on a side of the second gate metal layer away from the first gate metal layer;
forming a plurality of first signal line via holes and a plurality of second signal line via holes in an overlap area between the first insulating layer and the first output line portion; the plurality of first signal line via holes and the plurality of second signal line via holes penetrating the first insulating layer;
forming a source-drain metal layer on a side of the first insulating layer away from the second gate metal layer, performing a patterning process on the source-drain metal layer to form a first source-drain metal pattern and a second source-drain metal pattern, wherein the first source-drain metal pattern includes the second electrode of the first switch, and the second source-drain metal pattern includes the second electrode of the second switch, so that the first output line portion is coupled to the second electrode of the first switch through the plurality of first signal line via holes, and the first output line portion is coupled to the second electrode of the second switch through the plurality of second signal line via holes,
the plurality of first signal line via holes are sequentially arranged along the first direction, and the plurality of second signal line via holes are sequentially arranged along the first direction.
