摘要： A liquid crystal display (LCD) which includes a liquid crystal panel and a temperature-measurement apparatus. The temperature-measurement apparatus includes a temperature sensor which includes a variable-resistance element having a resistance that varies according to the temperature of the liquid crystal panel and a fixed-resistance element connected in series to the variable-resistance element, divides a first input voltage, and outputs a first temperature-dependent voltage that varies according to a temperature of the liquid crystal panel. A voltage divider which divides a second input voltage and outputs a reference voltage is provided. A differential amplifier receives at a first input the first temperature-dependent voltage and receives at a second input the reference voltage and amplifies a difference between the first temperature-dependent voltage and the reference voltage, and provides at an output a second temperature-dependent voltage.
