A liquid crystal display device includes a local dimming function that reduces the feeling of strangeness given to viewers caused by light leakage. A video display control portion controls the aperture ratio of liquid crystal pixel outside an image display area. A backlight control portion controls the brightness value of light emitting element that illuminate a region outside the image display area so as to be a predetermined value in response to control signals output from the video display control portion. A liquid crystal display device controls the brightness of the region outside the image display area so as to be a predetermined value on the basis of the correlation between the aperture ratio of the liquid crystal pixel outside the image display area and the brightness value of the light emitting element that illuminates the region outside the image display area.
