Abstract: A display device includes a display panel including first and second panel pads electrically connected to each other, a connection board including first and second connection board pads connected to the first and second panel pads, respectively, an output pad, and a driving circuit. The driving circuit includes a pull-up resistor connected between a first voltage terminal and a first node, and a comparator configured to compare a voltage at the first node with a reference voltage and to output a contact test signal corresponding to a comparison result to the output pad. The first connection board pad is electrically connected to the first node, and the second connection board pad is connected to a second voltage terminal.

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.
