Claim:
1. An active matrix substrate, comprising: a substrate; a plurality of gate bus lines that extend in a first direction on the substrate; a plurality of source bus lines that extend in a second direction that intersects said first direction on the substrate; a plurality of thin film transistors on the substrate that are respectively electrically connected to said plurality of gate bus lines and said plurality of source bus lines; a plurality of pixel electrodes on the substrate that are respectively electrically connected to drain electrodes of the plurality of thin film transistors and that are arranged in a matrix in the first and second directions; and a plurality of auxiliary capacitance bus lines that extend in said first direction, wherein each of the plurality of auxiliary capacitance bus lines has a plurality of auxiliary capacitance electrodes attached thereto, arranged in the first direction and each extending in the second direction, wherein each of the plurality of auxiliary capacitance electrodes includes a first electrode section and a second electrode section, wherein, in each of the plurality of auxiliary capacitance electrodes, at least a portion of said first electrode section overlaps one of said plurality of source bus lines, wherein, in each of the plurality of auxiliary capacitance electrodes, said second electrode section has two linear sections extending in said second direction, and at least a portion of a region between said two linear sections overlaps said one of said plurality of source bus lines, and wherein, in each one of the plurality of auxiliary capacitance bus lines, with respect to every adjacent two of the plurality of auxiliary capacitance electrodes attached to said one of the plurality of auxiliary capacitance bus lines, positions of said first electrode section and second electrode section in the second direction are alternated so as to be generally point-symmetric about a reference point on a straight line that passes through a central region of pixels arranged in the first direction along said one of the plurality of auxiliary capacitance bus lines.
