1. A display device comprising:
a first pixel coupled to a first data line;
a second pixel coupled to a second data line; and
a demux configured to couple a data supply line to either the first data line or the second data line,
wherein the demux comprises:
a first demux transistor including a first electrode coupled to the data supply line, a second electrode coupled to the first data line, and a main gate electrode and a sub-gate electrode coupled to a first select control line, and
a second demux transistor including a first electrode coupled to the data supply line, a second electrode coupled to the second data line, and a main gate electrode and a sub-gate electrode coupled to a second select control line, and
wherein a turn-on period of the first demux transistor is shorter than a turn-on period of the second demux transistor.
