Abstract
A liquid crystal display apparatus includes an active matrix substrate and a counter substrate opposing the active matrix substrate via a liquid crystal layer. The active matrix substrate includes: a display portion having a plurality of source lines, a plurality of gate lines crossing the plurality of source lines, a plurality of pixel electrodes arranged in a matrix in regions surrounded by the plurality of source lines and the plurality of gate lines, and switching elements for connecting the pixel electrodes to the source lines and the gate lines; and a first electrode provided along the source lines outside of the display portion, wherein the first electrode serves to produce a reference signal by changing a surface potential distribution of the substrate, and the positions of the plurality of pixel electrodes are determined based on the reference signal.
