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. The second converting circuit converts the inverted first data signal into a second gamma voltage. An output buffer stores the first and second gamma voltage outputs from the converter and then outputs them. Thus, although gamma voltage is interfered from the coupling between a signal line and a gamma voltage line, a user can have normal images regardless of s the gamma voltage variation. The present invention relates to charge-trapping memories in the application of display panels.
