Abstract
A liquid crystal driving device in accordance with the present invention includes an offset information storing register for storing digital compensation data, an amplitude information storing register, and a variable resistor for adjusting the maximum gradation display voltage and minimum gradation display voltage in order to cause an absolute value of the difference between a voltage applied to a pixel electrode and a voltage applied to a common electrode to be consistent in all frames. With this, the number of components of the liquid crystal driving device can be restrained and the offset adjustment can be easily carried out with low costs.
