Abstract: A liquid crystal display device includes a backlight module configured to switch between first light having a maximum luminance in a first direction and second light having a maximum luminance in a second direction different from the first direction and emit the first light and the second light from a main surface, a liquid crystal display panel, and a control device. The control device receives a first image and generates a first offset image based on the first image, the first offset image being an image obtained by reversing a color of the first image and having a luminance adjusted, controls the liquid crystal display panel such that a first display image including the first image and a second display image including the first offset image are alternately displayed, and controls the backlight module so that the first light is emitted when the first display image is displayed and the second light is emitted when the second display image is displayed. A luminance of the first offset image is substantially equal to a luminance in the second direction when the liquid crystal display panel displays the first display image.
