ABSTRACT:
A liquid crystal device is constituted by a pair of oppositely disposed substrates each provided with an alignment control layer, and a liquid crystal layer comprising a liquid crystal material and disposed between the substrates with a spacer member. In the device, the spacer member has an electrical conductivity larger than that of the liquid crystal material. Further, the liquid crystal layer containing the spacer member has a first resistance in a direction of a normal to the substrates in a prescribed temperature range substantially lower than a second resistance of a corresponding liquid crystal layer, in the identical direction, consisting only of the liquid crystal material and having the identical plane area and thickness. The liquid crystal device is effective in providing an improved drive margin in a wide temperature range while suppressing a DC offset voltage component applied to the liquid crystal layer.
