Abstract
Provided is a backlight unit () including a light source () where multiple light-emitting elements () are two-dimensionally laid out, and a wavelength converting member () that has a phosphor (), and that converts a wavelength of light from the light source, where a wavelength conversion capability varies in accordance with a distance to a light-emitting element that is closest of the multiple light-emitting elements, in order to reduce color unevenness that occurs depending on difference in distance between the light source and wavelength converting member of the backlight unit.
