Abstract:
1. A liquid crystal display device, comprising: a scanning line which becomes an on-voltage at every predetermined interval; a liquid crystal capacitor having a liquid crystal sandwiched between a counter electrode and a pixel electrode, the counter electrode being of a reference voltage that is unmodulated; a data line which becomes a voltage corresponding to a density on the basis of the reference voltage of said counter electrode and to a writing polarity of said liquid crystal capacitor when said scanning line is the on-voltage; a first switching element inserted between said data line and said pixel electrode, said first switching element being turned on when the on-voltage is applied to said scanning line, and being turned off when an off-voltage is applied; a storage capacitor having one terminal connected to said pixel electrode and other terminal; and a selector which, when the voltage of said data line corresponds to a positive-polarity writing during the period when the other terminal is the on-voltage, shifts the voltage of the other terminal to high after said scanning line turns off, and when the voltage of said data line corresponds to a negative-polarity writing during the period when the other terminal is the on-voltage, shifts the voltage of the other terminal to low after said scanning line turns off.
