A liquid crystal display device includes a liquid crystal panel, a backlight, a luminance control instruction receiving component, an inverter circuit, a backlight control component and an image quality adjustment component. The liquid crystal panel displays an image. The backlight emits light to the liquid crystal panel. The luminance control instruction receiving component receives a luminance control instruction to control a luminance of the liquid crystal display device. The inverter circuit controls the light of the backlight. The backlight control component sets a backlight control amount for controlling the inverter circuit within a specific range based on the luminance control instruction when the luminance control instruction receiving component receives the luminance control instruction. The image quality adjustment component performs an image quality adjustment of the image displayed on the liquid crystal panel according to the luminance control instruction when the luminance control instruction receiving component receives the luminance control instruction.
