ABSTRACT:
A liquid crystal device is provided comprising: a liquid crystal panel displaying grayscale levels by applying a driving signal to a pair of electrodes having liquid crystal interposed therebetween and displaying white when voltage is applied, the driving signal having a pulse width that is modulated according to the grayscale level; a temperature detecting unit detecting a temperature of the liquid crystal panel; a discrimination unit discriminating whether the temperature detected by the temperature detecting unit is a predetermined threshold value or more; and a pulse width defining unit that defines the pulse width according to the grayscale level such that the pulse width of the driving signal is gradually increased as the grayscale level becomes bright when the temperature is the threshold value or more; and changes the pulse width such that the pulse width corresponding to the darkest grayscale level is larger than the pulse width corresponding to that at which the temperature is the threshold value or more when the temperature is less than the threshold value.
