Array substrate, display panel, display device and repair method

An array substrate, comprising:

• a substrate;
• a plurality of gate line groups, disposed on a side of the substrate and extending in a first direction, wherein each gate line group comprises two gate lines extending in the first direction;
• a plurality of data lines extending in a second direction, wherein the second direction intersects with the first direction;
• a plurality of transistors, wherein each transistor comprises:
• a first electrode electrically connected with the data line, and a second electrode;
• wherein a part of an orthographic projection of the second electrode of the transistor on the substrate is located between orthographic projections of two gate lines of a same gate group on the substrate;
• a plurality of pixel electrode groups, wherein an orthographic projection of at least a part of the pixel electrode group on the substrate is located in a region formed due to intersection of the gate line groups and the data lines;
• and each pixel electrode group comprises:
• two pixel electrodes distributed in the first direction;
• and
• a plurality of first common lines, wherein an orthographic projection of the first common line on the substrate is located between the orthographic projections of the two gate lines of the same gate line group on the substrate, and at least part of the orthographic projection of the first common line on the substrate overlaps with at least part of the orthographic projection of the second electrode of the transistor on the substrate.
