PROBLEM TO BE SOLVED: To reduce after image when performing display with IP (Interlace-Progressive) conversion in a hold response type display. SOLUTION: In the display device, a plurality of drain electrode lines and a plurality of gate electrode lines are arranged like a matrix, and pixel areas are provided each of which is surrounded with two adjacent drain electrode lines and two adjacent gate electrode lines, and each pixel area has a TFT element, and a display area is set as a set of pixel areas, and a drain electrode line is electrically connected to a drain electrode of the TFT element, and a pixel electrode is electrically connected to a source electrode of the TFT element, and a signal having a positive polarity and a signal having a negative polarity are alternately applied to the pixel electrode respectively during the first number of frames, and a peculiar period when a signal having one polarity is applied to the pixel electrode continuously during the second number of frames larger than the first number of frames is provided, and a signal having a gradation lower than a preceding frame and a following frame is applied in the peculiar period.
