摘要：
A liquid crystal display device has a first backlight unit and a second backlight unit. The first backlight unit includes a first optical member that transmits light incident from the second backlight unit, converts light output from a light source to light having a narrow-angle directional distribution, and radiates the converted light toward the rear surface of the liquid crystal display panel. The second backlight unit includes a second optical member that converts light output from a light source to light having a wide-angle directional distribution, and radiates the converted light toward the rear surface of the liquid crystal display panel.
