Patent ID: 7190344

Claim:
A vehicle-use liquid crystal display device for displaying process data D such as a vehicle speed and an engine speed changing according to an operating state of a vehicle on a liquid crystal display panel, said liquid crystal display device comprising: temperature detection means for detecting a temperature of said liquid crystal panel; and display control means for displaying the process data D on said liquid crystal panel, wherein said display control means obtains a difference ΔD between the process data D and a display value Ddis, and when an absolute value of the difference ΔD exceeds a first reference value ΔDref1, switches display from a current display value into a new display value in response to the process data D within a temperature range in which the temperature of said liquid crystal panel is higher than a predetermined reference temperature, and does not switch the display value within the temperature range in which the temperature of said liquid crystal panel is lower than the predetermined reference temperature until the absolute value of the difference ΔD exceeds a second reference value ΔDref2 which is larger than the first reference value ΔDref1.
