A display device is provided which is capable of, at time of driving a display panel section, preventing noise caused by components exhibiting a piezoelectric effect and of achieving silent operations and removal of unpleasant audible noise. When load variation for each line has an audio frequency component, noise occurs in components exhibiting a piezoelectric effect such as a capacitor. A load variation detecting unit totalizes input display data for every line and, when it is estimated from an amount of variation of the values and variation period that an amount of variation of driving load is large and a variation period is within an audio frequency range, produces a display pattern representing a variation period and instructs a driver controlling unit to permute order of driving lines. The driver controlling unit searches a table for a pattern to be used and changes the variation period to be out of the audio frequency range to prevent occurrence of audible noise.
