摘要： A liquid crystal display device comprises an OCB-mode liquid crystal display panel including a liquid crystal layer in which the alignment state of liquid crystal molecules is transitioned in advance from a splay alignment to a bend alignment, and a display control section which applies a liquid crystal drive voltage to the liquid crystal layer according to a video signal. The display control section is configured to detect the application environment of the liquid crystal display panel and determine a minimum value of the liquid crystal drive voltage based on a phase-transition threshold voltage which causes energy of the splay alignment and energy of the bend alignment to be balanced with each other in the detected application environment.
