Liquid display and source electrode side fan-out area circuit thereof

Disclosed are a liquid display and a source electrode side fan-out area circuit thereof. The source electrode side fan-out area circuit comprises a first switch, a second switch, a third switch and a fourth switch which are controlled by a control signal jointly, the first switch is connected between a first output end and a first data line, the second switch is connected between the first output end and a third data line, switching action of the second switch is opposite to that of the first switch, the third switch is connected between a third output end and the first data line, switching action of the third switch is opposite to that of the first switch, and the fourth switch is connected between the third output end and the third data line, and switching action of the fourth switch is identical with that of the first switch. Consequently, transmission direction of sub-pixel signals can be changed by changing the control signal, and the liquid display is supportive of specific display applications.
