ABSTRACT:
A CPU is provided for producing a control signal. In accordance with the control signal, a modulated signal modulated in pulse width by the control signal is produced. The modulated signal has a predetermined duty ratio based on the control signal. A liquid crystal driving signal having the duty ratio based on the modulated signal is produced. The CPU is for producing the control signal for setting the duty ratio in accordance with a refractive index at each of the unit electrode of the liquid crystal panel.
