Thin film transistor array substrate and display panel

A display panel, comprising a color filter substrate, a thin film transistor array substrate, and a liquid crystal layer between the color filter substrate and the thin film transistor array substrate, the thin film transistor array substrate comprising:

• a substrate;
• a first conductive layer on the substrate, the first conductive layer defining a plurality of scan line pairs, each of the plurality of scan line pairs comprising a first scan line and a second scan line both extending in a first direction;
• a second conductive layer on a side of the first conductive layer away from the substrate, the second conductive layer defining a plurality of data lines and a plurality of common lines both extending in a second direction intersecting with the first direction, the plurality of data lines and the plurality of common lines alternately arranged in the first direction;
• and
• a plurality of pixel units, each of the plurality of the pixel units being between adjacent two of the plurality of common lines, each of the plurality of the pixel units comprising a first sub-pixel and a second sub-pixel located on opposite sides of one of the plurality of scan line pairs, the first sub-pixel electrically connected to the first scan line, the second sub-pixel electrically connected to the second scan line, the first sub-pixel and the second sub-pixel located on opposite sides of and electrically connected to one of the plurality of data lines;
• wherein each of the plurality of common lines comprises a plurality of bridges, each of the plurality of bridges crosses one of the plurality of scan line pairs;
• a projection of each of the plurality of bridges on the substrate overlaps with projections of both the first scan line and the second scan line on the substrate, and an area of a portion of the first scan line that overlaps with the bridge equals to an area of a portion of the second scan line that overlaps with the bridge;
• each of the plurality of bridges completely overlaps with a portion of one of the plurality of scan line pairs extending in the second direction.
