A liquid crystal display device of the present invention includes: first and second electrodes crossing each other; switching elements in a vicinity of each first and second electrode intersection; pixel electrodes respectively arranged in a matrix and partitioned from one another by the first and second electrodes; the first electrodes supplied with a gate voltage for turning ON/OFF the switching elements and the second electrodes supplied with a source voltage; third electrodes supplied with a common voltage; and a liquid crystal layer interposed between the third electrodes and the pixel electrodes. The source voltage includes an image signal voltage and an assist signal voltage. The common voltage has different values between an image signal writing scanning period defined as a period during which the image signal voltage is applied, and at least one assist signal writing scanning period defined as a period during which the assist signal voltage is applied.
