Abstract
A liquid-crystal display device has a display that includes a display face, a plurality of first light sources, each of which emits a first light to a face on an opposite side of the display face, a second light source that differs from the first light source and emits a second light, and a scanner that scans the second light in the face. The scanner scans the second light in a predetermined region within a region to which the first light is irradiated. The second light overlaps the first lights in the predetermined region.
