Abstract
A display device is provided. A display device of one embodiment comprises a plurality of sub pixels, a plurality of data lines connected to each of the plurality of sub pixels, and a multiplexer (MUX) circuit connected to a pair of adjacent data lines among the plurality of data lines, the MUX circuit comprising a charge transistor connected to each of the pair of data lines, and a discharge transistor connected to each of the pair of data lines. Accordingly, the MUX circuit comprises the discharge transistor discharging a voltage of the data line, to reduce or minimize a failure of abnormal driving of sub pixels connected to a part of the data lines.
