1. A liquid crystal display device that has a number of pixels, which are arranged in columns and rows to form a matrix pattern, the device comprising:

  • an active-matrix substrate that includes pixel electrodes, each of which is provided for an associated one of the pixels, a plurality of scan lines that run in a row direction, and a plurality of signal lines that run in a column direction;

    a counter substrate that faces the active-matrix substrate;

    a liquid crystal layer that is interposed between the active-matrix substrate and the counter substrate; and

    a signal line driver that applies a positive or negative grayscale voltage as a display signal to each said signal line,wherein those pixels include m kinds of (where m is an even number that is equal to or greater than four) pixels that display mutually different colors, andwherein the pixels are arranged so that n out of the m kinds of pixels (where n is an even number that is equal to or smaller than m and is a divisor of m) are repeatedly arranged in the same order in the row direction, andwherein each of the rows of pixels that are formed by those pixels includes multiple groups of pixels, to each of which n pixels that are arranged consecutively in the row direction belong, grayscale voltages of mutually opposite polarities being applied through associated signal lines to the pixel electrodes of two arbitrary pixels that are adjacent to each other in each said group of pixels, andwherein in two arbitrary ones of those groups of pixels that are adjacent to each other in the row direction, grayscale voltages of mutually opposite polarities are applied through their associated signal lines to the pixel electrodes of pixels that display the same color, andwherein the signal lines include at least one pair of signal lines that are adjacent to each other and that supply grayscale voltages of the same polarity, andwherein the source-drain capacitance of the pixels that are located between the pair of signal lines is smaller than the source-drain capacitance of the other pixels.
