摘要： In a liquid crystal drive controller formed as a semiconductor integrated circuit having therein a power source circuit including a boosting circuit and driving a source line and a gate line of a TFT liquid crystal panel, the number of external capacitive elements and the number of external terminals for connecting the external capacitive elements are reduced, thereby reducing the size and cost of the chip and an electronic device on which the chip is mounted. As a boosting circuit for generating a voltage for driving a source line of the TFT liquid crystal panel in the liquid crystal controller having therein the power source including the boosting circuit, a boosting circuit having an external capacitive element is used. On the other hand, as a boosting circuit for generating a voltage for driving a gate line, a charge pump having a built-in (on-chip) capacitive element is used.
