A display control circuit includes a vertical timing control circuit that generates first and second start signals, a panel driving unit that sequentially drives OCB liquid crystal pixels in units of one row under the control of the first start signal to hold pixel voltages for gradation display in the pixels of the driven row, and that sequentially drives the pixels in units of at least one row under the control of the second start signal to hold pixel voltages for black insertion in the pixels of the driven row, and a light source driving unit that drives backlight sources, which are arranged substantially in parallel to the rows of the pixels to divide the pixels into groups each including at least two neighboring rows of pixels, and each of which principally illuminates the pixels of the associated group. In particular, the light source driving unit is configured to start, in synchronism with the first start signal, an operation for sequentially blinking the backlight sources with a predetermined duty ratio corresponding to a ratio between a holding period of the pixel voltage for gradation display and a holding period of the pixel voltage for black insertion, and to turn off each of the backlight sources before all the liquid crystal pixels of the associated group are driven for black insertion.
