A liquid crystal apparatus is provided a liquid crystal display comprising scanning electrodes, data electrodes disposed opposite to and intersecting with the scanning electrodes so as to form an electrode matrix, and a ferroelectric liquid crystal disposed between the scanning electrodes and data electrodes. A first circuit is further provided for applying a scanning selection signal having a duration of one scanning selection period 1H to the scanning electrodes and applying data signals to the data electrodes in synchronism with the scanning selection signal so as to apply a drive voltage having an amplitude VOP to the liquid crystal. A control circuit controls the first circuit so as to change the one scanning selection period 1H by a change DELTA 1H and the drive voltage amplitude VOP by a change DELTA VOP corresponding to a change in ambient temperature, the changes DELTA 1H and DELTA VOP satisfying the following formula (1): -0.8>/= DELTA log 1H/ DELTA log VOP>/=-1.4 (1), wherein DELTA log 1H1=log(1H1+ DELTA 1H)-log 1H, and DELTA log VOP=log(VOP1+ DELTA VOP)-log VOP1, 1H1 being one scanning selection period before the change, VOP1 being the drive voltage amplitude before the change.
