Abstract:
This finder display device is provided with a liquid crystal panel, a backlight, and a light source driving section. The backlight has a light guide having a side near which first to sixth light sources are disposed. The light source driving section sets the first and fifth light sources as a first sub-light source group, the second and sixth light sources as a second sub-light source group, and the third and fourth light sources as a third sub-light source group, and periodically supplies driving pulses to the first to third sub-light source groups at respectively different timings. The light source driving section controls the amounts of light of the light source groups by changing the pulse widths of the driving pulses.
