Multi-domain liquid crystal display device

DETAILED DESCRIPTION In view of the above, it is an object of the present invention to provide a multi-domain liquid crystal display device capable of making more reliable the effects obtained by the technology disclosed in the Japanese Patent Application No.
Hei11-180615, of solving problems associated with conventional technologies including increased complicated processes such as microfabrication processes required for fabricating a common electrode and necessity for highly sophisticated laminating technology and of providing sharp contrast and excellent viewing angle characteristics.
According to a first aspect of the present invention, there is provided a multi-domain liquid crystal display device including: a liquid crystal held and put between a pair of substrates; two or more gate bus lines formed on one of the substrates and extending horizontally; two or more drain bus lines extending vertically; a plurality of pixels each being formed corresponding to each point of intersection of the gate bus lines and the drain bus lines and being arranged in a matrix form; and whereby each pixel described above is provided with a switching device to select a desired pixel, with a pixel electrode and with a control electrode operating to form two or more orientation areas within one pixel by generating a skew electric field acting on the liquid crystal and wherein the control electrode is connected to one of terminals of the switching device and a coupling capacitor is connected between the pixel electrode and the control electrode and wherein a signal voltage is applied from the corresponding drain bus line through the corresponding switching device at a time of selecting the corresponding gate line and a partial voltage of the signal voltage is applied to the pixel electrode through the coupling capacitor.
In the foregoing, a preferable mode is one wherein the pixel electrode is formed under the control electrode and an interlayer dielectric is formed between the pixel electrode and the control electrode
