A driving circuit of a liquid crystal display includes: a timing controller to output a gate control signal and a data control signal to control driving of a gate driving unit and a data driving unit and to output digital video data; a pair of gate driving units to be alternately driven by using at least one frame as a period to supply gate signals to gate lines of a liquid crystal panel in response to the gate control signal; and a data driving unit to supply pixel signals to data lines of the liquid crystal panel in response to the data control signal. Degradation of characteristics of transistors constituting each gate driver can be prevented.
