PROBLEM TO BE SOLVED: To eliminate the image quality defect due to the display unevenness of a non-display region when eliminating the image quality defect due to the impurity ions in a liquid crystal in a display region by moving the impurity ions to the non-display region. SOLUTION: In a period when a video signal is not written to signal lines 22-1 to 22-n from a horizontal driver 33, for example, in a vertical blanking period, a precharge signal Psig is supplied to a pixel electrode of each pixel of the non-display regions B, C to AC drive each pixel within the non-display regions B, C.
