Abstract
An object is to provide a liquid crystal display device, which can be driven with low power consumption while keeping display quality. A liquid crystal display device includes a plurality of first vertical scanning lines and a plurality of horizontal scanning lines formed on a substrate in a matrix form; first switching means connected to the horizontal scanning lines and being controllable by the first vertical scanning lines; control capacitor elements for holding control signals on the horizontal scanning lines connected to the first switching means; and second switching means for connecting pixel signal lines and pixel electrodes together to write the potentials on the pixel signal lines to the pixel electrodes, the second switching means being connected to the control capacitor elements.

- and
- second switching means for connecting a pixel signal line and a pixel electrode together to write the potential on the pixel signal lines to the pixel electrodes,
- said second switching means being connected to said control capacitor elements.
A liquid crystal display device comprising:
- a plurality of first vertical scanning lines and a plurality of horizontal scanning lines formed on a substrate in a matrix form;
- a pixel electrode selected by said vertical scanning line and said horizontal scanning line;
- and
- a control capacitor element for holding a control signal on said horizontal scanning line, wherein
- said pixel electrode is connected to first and second reference lines via independent switching means, respectively, and at least one of said switching means is a second switching means being controlled by said control capacitor element.
A liquid crystal display device, wherein
- fifth switch means being controllable by the first vertical scanning line is connected in series between the n-type TFT forming the second switching means and the pixel electrode, and sixth switching means being controllable by the third vertical scanning line is connected in series between the n- and p-type TFTs forming the second switching means and the pixel electrode.
