Abstract: In a data driver, an inverter inverts a first data signal from a first group of data signals. A converter includes first and second converting circuits. The first converting circuit converts a second data signal included from second group of data signals into a first gamma voltage. The second converting circuit has a circuit configuration inverted with respect to the first converting circuit.
