Abstract
To reduce current noise by reducing the current peak value and the current rise slope, a data driver includes a delay unit and a plurality of output circuits. The delay unit sequentially delays a control signal and outputs delay control signals. The output circuits start outputting in response to the delay control signals. The delay unit generates the delay control signals to be output to the output circuits.
