A data line driving circuit drives data lines of an electro-optical panel, which occupies a small area and can drive the data lines with low power consumption. When the digit of the most significant bit is "0", all of the gamma-correction switches are in an on-state. Thus, the gamma-correction is not performed. Conversely, when the digit of the most significant bit is "0", the gamma-correction switches are put into an on-state according to the data value represented by low order bits. Thus, the gamma-correction is performed. That is, whether or not the gamma-correction is performed can be determined according to which of the white side and the black side the gray scale level to be displayed is on. Furthermore, irrespective of whether or not the gamma-correction is performed, DAC capacitances are used for both the cases that the gamma-correction is performed, and that gamma-correction is not performed. Thus, the size of the circuit can be reduced.
