1. An active matrix substrate, comprising:

  • a plurality of scan lines extending along a first direction, the plurality of scan lines including a first scan line and a second scan line that are adjacent to each other;

    a plurality of signal lines extending along a second direction, the plurality of signal lines including a first signal line and a second signal line that are adjacent to each other;

    a plurality of pixels arranged in a matrix, the plurality of pixels including a first pixel and a second pixel that are adjacent to each other along the second direction;

    an auxiliary capacitance line;

    a first pixel electrode for the first pixel and a second pixel electrode for the second pixel that are disposed in a region surrounded by the first scan line, the second scan line, the first signal line, and the second signal line;

    a first TFT for the first pixel, the first TFT being connected to the first signal line;

    a second TFT for the second pixel, the second TFT being connected to the second signal line;

    an auxiliary capacitance electrode connected to the auxiliary capacitance line, the auxiliary capacitance electrode extending under the first pixel electrode and the second pixel electrode;

    a first auxiliary capacitance opposite electrode for the first pixel, the first auxiliary capacitance opposite electrode being connected to the first pixel electrode; and

    a second auxiliary capacitance opposite electrode for the second pixel, the second auxiliary capacitance opposite electrode being connected to the second pixel electrode,wherein the auxiliary capacitance line extends along the second direction,wherein the first TFT is positioned on a positive side of the auxiliary capacitance line along the first direction,wherein the second TFT is positioned on a negative side of the auxiliary capacitance line along the first direction,wherein the auxiliary capacitance line extends along the second direction while bending,wherein the first auxiliary capacitance opposite electrode is positioned on said positive side of the auxiliary capacitance line along the first direction, andwherein the second auxiliary capacitance opposite electrode is positioned on said negative side of the auxiliary capacitance line along the first direction.
