Claim Text:
1. A liquid crystal display device comprising: an array substrate comprising a plurality of pixel electrodes arranged in a matrix, a plurality of gate lines extending in a row direction in which the pixel electrodes are arranged, a plurality of source lines extending in a column direction in which the pixel electrodes are arranged, a plurality of switching elements, a gate driver configured to sequentially drive the gate lines, and a source driver configured to apply gradation signals to the source lines, and each of the switching element being disposed in proximity to a position where a corresponding pair of the gate lines and source lines crosses each other; a counter substrate comprising a color filter including a transparent filter, a red filter, a green filter, and a blue filter arranged periodically in the row direction, each of the transparent, red, green, and blue filters facing one corresponding column of the pixel electrodes; and a liquid crystal layer held between the array substrate and the counter substrate, wherein in each frame period, for the pixel electrodes, the gradation signals of a given polarity are applied to all pixel electrodes facing the transparent filter, while the gradation signals of the reverse polarity are applied to all pixel electrodes facing the green filter, and in each frame period, for the pixel electrodes, the gradation signals of a same polarity are applied to all the pixel electrodes facing the transparent filter and a plurality of pixel electrodes facing the red filter, while the gradation signals of a same polarity are applied to all the pixels electrodes facing the green filter and a plurality of pixel electrodes facing the blue filter.
