Abstract
A liquid crystal display device comprises a first substrate, plural pixel electrodes arranged in rows and columns on the first substrate, plural switching elements, an end of the conduction path of each of the switching elements being connected to a corresponding one of the pixel electrodes, a second substrate that is opposed to the first substrate, a common electrode formed on the second substrate and opposed to the pixel electrodes, a liquid crystal material with spontaneous polarization sandwiched between the first and second substrates, plural signal line bundles arranged on the first substrate substantially parallel with one another along the columns, each of the signal line bundles comprising a predetermined number of signal lines and each of the signal lines being connected to the other end of the conduction path of each of selected switching elements arranged along a corresponding one of the columns, plural scanning lines arranged on the first substrate substantially parallel with one another along the rows and connected to the control terminals of the switching elements, and plural drivers each for driving a predetermined number of scanning lines. The drivers correspond in number to the signal lines of each of the signal line bundles, and each of the drivers drives corresponding scanning lines.
