摘要： A liquid crystal display device includes a liquid crystal display element section that is initialized such that the alignment state of liquid crystal molecules is transitioned from a splay alignment to a bend alignment capable of displaying an image, and a driving circuit DR that cyclically applies, after the initialization, to the liquid crystal display element section a reverse transition prevention voltage, which prevents reverse transition from the bend alignment to the splay alignment, and a display voltage corresponding to a display signal supplied externally. In particular, the driving circuit DR is configured to alter a reverse transition prevention driving condition on the basis of a field frequency of the display signal.
