Abstract
A liquid crystal display apparatus having a pair of substrates of which at least one is transparent; and a liquid crystal layer supported between the pair of substrates, in which one of the pair of substrates has a plurality of row lines and a plurality of row lines, and pixels are placed corresponding to intersections of the plurality of row lines and the plurality of row lines. A first pixel electrode and a second pixel electrode are provided in the pixel, and a first active element is placed in the pixel and an output terminal thereof is connected to one row line adjacent to the first pixel electrode and the pixel, and a second active element is placed in the pixel and its output is connected to the other row line adjacent to the second pixel electrode. The first and second active elements are brought into conduction during a period of writing a voltage to a liquid crystal, and the first and second active elements are brought into a high resistance state during a holding period, and a difference voltage between the adjacent row lines is applied to the liquid crystal to display an image. A capacitance between the row line and the first pixel electrode and that between the row line and the second pixel electrode are equal as to each row line adjacent to the pixel.
