Zusammenfassung:	Provided is a liquid crystal display device that includes an effective pixel portion, a pixel drive portion, and a dummy pixel portion adjacent to the effective pixel portion. The effective pixel portion comprises effective pixels contributing to display. The dummy pixel portion includes dummy pixels not contributing to the display. The pixel drive portion drives the effective pixels of the effective pixel portion and the dummy pixels of the dummy pixel portion by reversing a voltage applied to a liquid crystal with a given period with a reference voltage as a center. The effective pixels and the dummy pixels each have a pixel transistor and a retention capacitor. In addition, with respect to retention characteristics of a pixel electric potential in relation to the reference voltage, the retention characteristics of the dummy pixel portion are made asymmetrical relative to the retention characteristics of the effective pixel portion.
