Abstract
A source driver () includes: a first amplifier circuit and a second amplifier circuit each amplifying either one of input signals that are in-phase and antiphase; and a switching control circuit () which supplies an offset switching signal () for switching the input signals, the switching control circuit () supplying the offset switching signal () having a higher frequency than a horizontal synchronization signal. This provides a display drive circuit capable of enhancing a display quality while preventing a flicker from occurring in an entire display screen.
