A display apparatus includes first to third demultiplexer circuits respectively providing a data signal, supplied from a data driver, to three data lines. Each of the first to third demultiplexer circuits includes a switching unit providing the data signal to a corresponding data line of the three data lines on the basis of a voltage of a corresponding control line of first to third control lines, a voltage controller controlling the voltage of the corresponding control line in response to a corresponding time division control signal of first to third time division control signals and a corresponding auxiliary signal of first to third auxiliary signals which partially overlap the first to third time division control signals respectively, and a voltage discharger discharging the voltage of the corresponding control line.
