The present invention discloses an LCD device. The LCD device employs pre-charging within a frame accompanying high and low levels signal of array common lines. Each pixel is charged a high voltage before writing into a correct data signal, that is, the over driving is performed before the correct data signal is written into the pixel. The present invention also discloses a signal driving method for the LCD device. Compared with the prior art, the frame buffer is not required in the present invention on one hand; the over driving can be performed without complex timing functions on another hand; and the incorrect twist angles of the liquid crystals which are driven instantaneously can be significantly avoided when using the conventional over driving by a look-up table for comparing two sequential image signals.
