A vehicle-use liquid crystal display device which is capable of securing high visibility even under a low temperature environment without increasing or enlarging power consumption is provided.A display vehicle speed Ddis is switched according to a hysteresis of .+-.0.7 kilometer per hour as shown in FIG. 6(b) under a normal or high temperature environment of not less than 45.degree. C. with respect to a change in a vehicle speed shown in FIG. 6(a). Namely, even if the vehicle speed D changes between 51.4 kilometers and 52.6 kilometers, the display vehicle speed Ddis is held at 52 kilometers. The display vehicle speed Ddis is switched according to a hysteresis of .+-.1.0 kilometer per hour as shown in FIG. 6(c) under a low temperature environment of less than 45.degree. C. Namely, even if the vehicle speed D changes between 51.1 kilometers and 52.9 kilometers, the display vehicle speed Ddis is held at 52 kilometers.
