The liquid crystal display device (1) includes a liquid crystal panel (69) having, for each of pixels (60), a digital memory element (68) for holding an electric potential according to image data and a liquid crystal cell (64) for displaying an image by receiving the electric potential from the digital memory element (68); and a liquid crystal driver circuit (10) having an AC control section (22) for reversing a polarity of an AC voltage applied to the liquid crystal cell (64) on a given cycle and an image transmission control section (21) for issuing instruction on outputting of image data to the liquid crystal panel (69). In a case where an image data transmission period contains a period during which a voltage in the liquid crystal cell (64) is reversed in response to a polarity reversal of the AC voltage applied to the liquid crystal cell (64), the image transmission control section (21) causes image data to be outputted to the liquid crystal panel (69) after the polarity reversal of the voltage in the liquid crystal cell (64) is completed. This makes it possible to (i) prevent a decrease in reliability of liquid crystal, (ii) update, without rewriting data, an image to be displayed, and (iii) prevent a deterioration in quality of a displayed image.
