Abstract

A liquid crystal display device includes: a display unit configured to pixels in a display region, a pixel drive circuit configured to apply voltage to liquid crystals, a memory configured to store therein a setting signal indicating whether to apply voltage to the liquid crystals in the display region, and two switch elements for switching coupling with the pixel drive circuit; and a controller configured to rewrite the setting signal stored in the memory when a mode in which the display unit is operated is switched, between a first mode causing the display unit to perform display output in accordance with a gradation signal generated based on image data, and a second mode causing the display unit to perform display output in accordance with the setting signal stored in the memory.
