LIGHTING DEVICE AND IMAGE DISPLAY DEVICE

摘要

A lighting device includes: a first light source group having first light sources partitioned into sections and controlled to light for each section; and a second light source group having second light sources partitioned into sections and controlled to light for each section. The second light source has a light distribution different from the first light source. The first and second light source groups are allowed to light independently of each other. The first light sources are arranged in a first array pattern allowing a uniform in-plane-distribution of luminance at a predetermined distance therefrom when whole of the first light source group is under lighting condition. The second light sources are arranged in a second array pattern different from the first array pattern. The second array pattern allows a uniform in-plane-distribution of luminance at the predetermined distance therefrom when whole of the second light source group is under lighting condition.
