Abstract:
1. A liquid crystal display device including, in one picture element, a plurality of sub-picture-element regions having transmittance-applied voltage characteristics which are different from one region to another, which comprises: first and second substrates arranged opposite to each other; a liquid crystal layer made of liquid crystal filled in the space between the first and the second substrates; a polymer which is formed in the liquid crystal layer, and which determines alignment orientations of liquid crystal molecules while a voltage is being applied; a spacer which is arranged in any one of a sub-picture-element region, which has the lowest threshold voltage of the transmittance-applied voltage characteristic among the plurality of sub-picture-element regions in the one picture element, and a region adjacent to the sub-picture-element region, and which determines the thickness of the liquid crystal layer; a switching element supported by the first substrate; a control electrode in said first picture element, the control electrode being directly connected to the switching element; an insulating film provided over at least the switching element and the control electrode; a plurality of sub-picture-element electrodes in said one picture element on the insulating film; wherein a sub-picture-element electrode, among the plurality of sub-picture-element electrodes, is arranged in the sub-picture-element region having the lowest threshold voltage of the transmittance-applied voltage characteristic is electrically connected to the control electrode, wherein sub-picture-element electrodes, among the plurality of sub-picture-element electrodes, arranged respectively in the other sub-picture-element regions are capacitively coupled with the control electrode via the insulating film; and wherein a plurality of slits are formed in each of the plurality of sub-picture-element electrodes in said one picture element.
