A display device includes a display panel, a first light source, and second light source. The first and second light sources are respectively aligned with a first spot and second spot in a direction perpendicular to a substrate. The first light source irradiates the first and second spots with luminance of a first value and second value, respectively. The first light source irradiates a midpoint between the first and second spots with a luminance value that is half the addition of the first and second values.
