A pixel driving circuit of an LCD is provided to complete a charging operation fast by performing precharging during a normal operation and another precharging in an actual precharging operation. A two transistors are provided in respective pixel areas on a liquid crystal panel of a matrix structure, and gates of the two transistors are respectively connected to upper and lower gate lines(Gn,Gn+1,Gn+3). Drain and source terminals are respectively connected to a data line, a liquid crystal cell and a storage capacitor for performing precharging by normal driving and performing another precharging separately. Drains of the two transistors placed in the respective pixel areas are connected to the same data line. |
