1. A liquid crystal display device comprising:
an array of pixels each having a memory function; a first buffer to supply a common voltage to a counter electrode of a liquid crystal capacitor, a second buffer to output a first voltage that is in phase with the common voltage, and a third buffer to output a second voltage that is in opposite phase with the second voltage, wherein each of the pixels supplies one of a first voltage and a second voltage to a pixel electrode of the liquid crystal capacitor according to a data value stored in the each of the pixels, the common voltage, the first voltage, and the second voltage have a same amplitude, the first buffer, the second buffer, and the third buffer commonly have a power supply; the frequency of the common voltage, the first voltage, and the second voltage is 120 Hz. |
