At least one slit is formed to control, upon electrification of honeycomb body, the flow of electricity therein and consequently the heat generation therein. In order to make lower the temperature of the end of each outer slit close to each of the electrodes attached to the honeycomb body, than the temperature of the center of honeycomb body or the temperature of the end of each inner slit, the thickness of partition walls is made larger at the intersection points of partition walls, in the passages surrounding said end of each outer slit, or the cell number between two adjacent slits is made larger in outer slits close to each of the electrodes attached to the honeycomb body, than in inner slits. This honeycomb body can prevent cell rupture from occurring during repeated electrification and has excellent durability.

摘要： A liquid crystal cell which minimizes disordered orientation occurring with temperature changes even across a wide range, to exhibit good contrast and high reliability, as well as a smectic liquid crystal composition for use the liquid crystal cell are provided. In smectic liquid crystal compositions having a layer construction in the liquid crystal molecular arrangement, it was found that antiferroelectric liquid crystal compositions resistant to variation in the layer spacing of the smectic phase due to temperature changes are resistant to disordered orientation. Specifically, if the antiferroelectric liquid crystal composition contains at lest 45 wt % of an antiferroelectric liquid crystal compound with roughly constant layer spacing in a temperature range from the temperature t.sub.1 which gives the minimum value for the layer spacing of the smectic C.sub.A * phase to -20.degree. C., no disordered liquid crystal orientation results even after cold/hot temperature cycles. An even greater effect is achieved if the spontaneous polarization at of the composition at temperature t.sub.1 is at least 160 nC/cm.sup.2.
