Abstract
A liquid crystal device includes a plurality of pixels disposed in the shape of a matrix of n rows×m columns (where n and m are natural numbers equal to or larger than two), n scanning lines, 2m data lines including pairs of a first data line and a second data line for each column of the plurality of pixels, and a data line driving circuit that generates a first gray scale voltage corresponding to higher bits acquired by dividing gray scale data of plural bits into the higher bits and lower bits and generates a second gray scale voltage corresponding to the lower bits. Each one of the plurality of pixels includes a first switching element and a second switching element which are controlled to be turned on or off by the common scanning lines, a first pixel electrode to which the first or second gray scale voltage is supplied from the first data line through the first switching element, and a second pixel.
