The present invention improves, in a display device to which normal display data and interpolation data are inputted from the outside, the moving image performance by applying overdrive processing to both of a bright frame and a dark frame. The display device includes a display panel having a plurality of sub pixels, and a driver for outputting a video voltage corresponding to the display data to the respective sub pixels. The display data inputted from the external system is constituted of normal display data and interpolation display data inserted between the normal display data. The signal generation circuit includes an overdrive circuit for applying overdrive processing to the normal display data and the interpolation display data inputted from the external system, and a gray scale conversion circuit for converting the gradation of display data applied overdrive by the overdrive circuit. Assuming two continuous frame periods as one unit and assuming the display data inputted from the external system within the two continuous frame periods as first display data and second display data, when the display data inputted from the external system is of an intermediate gray scale, gray scale based on the second display data after conversion is set lower than gray scale based on the first display data after conversion.
