PURPOSE: A temperature compensating circuit of an LCD(liquid crystal display) is provided to stabilize an operating voltage to be applied in an LCD panel, and to reduce a consumption electric power of the LCD panel. CONSTITUTION: A temperature compensating circuit of an LCD provides a normal operating voltage to an LCD panel(40) even in a high temperature and a low temperature, and consists of a temperature detecting and compensating portion(10), a buffer(20), and a filter(30). The temperature detecting and compensating portion detects the environment temperature, and generates various operating voltages compensated depending on the detected temperature. Therefore, it is possible to a normal operating of the LCD panel. The buffer transmits the operating voltage of the temperature detecting and compensating portion. The filter eliminates a noise component of the operating voltage generated from the temperature detecting and compensating portion and the buffer, and provides the operating voltage without the noise component to the LCD panel.
