1. A display device, comprising:
a pixel unit including a plurality of pixel columns, each including a plurality of sub-pixels;
a source driver including a first output buffer configured to alternately output a first color data voltage and a second color data voltage through a first data line during one data write period including a first sub-period and a second sub-period,
wherein the second sub-period is subsequent to the first sub-period; and
a demultiplexer including a first select transistor connected between the first data line and a first sub-data line corresponding to a first pixel column among the plurality of pixel columns, and a second select transistor connected between the first data line and a second sub-data line corresponding to a second pixel column among the plurality of pixel columns,
wherein the demultiplexer is configured to connect the first data line and the first sub-data line during a first sub-period of a first data write period, connect the first data line and the second sub-data line during a second sub-period of the first data write period and a first sub-period of a second data write period, and connect the first data line and the first sub-data line during a second sub-period of the second data write period.
