The invention discloses a driving compensating circuit, a liquid crystal display device with the driving compensating circuit and a driving method. The liquid crystal display device includes the following components of: pixel units; a data line for transmitting data to the pixel unit; a scanning driver which includes a driving signal end, a first clock end, a second clock end and a compensation signal end, wherein the driving signal end outputs scanning signals, the first clock end and the second clock end output first and second clock signals, the compensation signal end outputs compensation signals; the driving compensating circuit which is connected with the scanning driver and is switched on according to the first and second clock signals and merges the scanning signals and compensation signals which are received from the scanning driver, and outputs merged compensation-scanning signals; and a scanning line which transmits the compensation-scanning signals to the pixel units. With the driving compensating circuit and the driving method provided by the invention adopted, the voltage of the front-end pixel unit and the voltage of the rear-end pixel unit of the liquid crystal display device can achieve saturated states, and therefore, the display quality of the liquid crystal display device can be improved.
