An integrated circuit device includes a plurality of data line driver circuits, a first correction D/A conversion circuit, and a plurality of D/A conversion circuits. Each of the data line driver circuits includes an operational amplifier, an input capacitor, and a first correction capacitor. Each of the D/A conversion circuits outputs an output signal to the input capacitor. The first correction D/A conversion circuit outputs a correction output voltage to the first correction capacitors to correct data signals output from the data line driver circuits.
