Liquid crystal display device and its driving method

A liquid crystal display device and its driving method of the present invention have a voltage application scheme to control a stable condition of a gap between pixels, by applying a voltage to a liquid crystal panel (1) in which ferroelectric liquid crystal is sandwiched between substrates (2, 3) each having a plurality of electrodes (4, 5). It is possible to implement the black matrix conditions with a simple configuration without a light shielding layer by controlling the stable condition of the gap, to display a grey tone with a combination of pixels and a gap, or to raise the opening ratio by making the condition between adjacent pixels and a gap the same condition.
