Display substrate and display apparatus

A display substrate, comprising:

• a base;
• a plurality of pixel units located on the base and arranged in columns in a first direction and in rows in a second direction, a pixel unit including a thin film transistor (TFT), the first direction intersecting with the second direction;
• a plurality of data lines located on the base, arranged in the second direction and extending in the first direction, the TFT being connected to a data line;
• wherein in a column of pixel units, TFTs of any two adjacent pixel units are located at a first side and a second side of a respective data line, the first side and the second side are opposite sides of the same data line;
• a plurality of first gate lines located on the base, arranged in the second direction and extending in the first direction;
• a plurality of second gate lines located on the base, arranged in the first direction and extending in the second direction;
• each second gate line being connected to a row of pixel units and at least one of the plurality of first gate lines, first gate lines connected to different second gate lines being different;
• and
• at least one gate driver circuit located on the base and connected to the plurality of first gate lines, the at least one gate driver circuit being disposed on a side of the display substrate parallel to the second direction;
• wherein any two adjacent columns of pixel units have a gap therebetween, at least one data line is disposed in each gap, and one first gate line is disposed in each of at least part of gaps;
• the at least one data line disposed in the gap includes one data line;
• and
• the first gate line includes a plurality of first extension portions and a plurality of second extension portions arranged alternately, each first extension portion extends in the first direction, each second extension portion extends in the second direction, any two adjacent first extension portions are respectively located at opposite sides of a column of pixel units, and any two adjacent second extension portions are respectively located at opposite sides of a row of pixel units.
