Abstract
A display device () includes a display panel (), a first light source (E), and second light source (F). The first and second light sources (E, F) are respectively aligned with a first spot () and second spot () in a direction perpendicular to a substrate (). The first light source (E) irradiates the first spot () and a third spot (M) with luminance of a first value, and irradiates the second spot () with luminance of a second value. The first light source (E) irradiates a midpoint (N') between the first and second spots with a luminance value that is half of the addition of the first value and second value.
