Abstract
Provided is a data driver including a digital to analog converter configured to convert image signal data into a plurality of data voltages, and an output buffer unit including a plurality of channels for outputting the plurality of data voltages. The output buffer unit includes a plurality of output blocks. Each output block includes one or more channels. Data voltages outputted from a first output block among the plurality of output blocks are delayed with a first time difference. Data voltages outputted from a second output block among the plurality of output blocks are delayed with a second time difference which is different from the first time difference.
