A backlight in which a reflector is secured to a chassis disposing a mounted substrate mounting light emitting diodes between the reflector and the chassis by a lamp clip for holding lamps and the mounted substrate is connected to a drive substrate outside the chassis and also relates to a liquid crystal display device provided with the backlight and a liquid crystal panel. The backlight and the liquid crystal display device capable to detect colors accurately by blocking light transmitted other than through a transparent part of a lamp clip and prevent light from escaping through fitting holes for the lamp clip into a space outside a chassis are provided. A cover surrounding a photodiode and through holes to transmit light from the clip to an LED drive substrate is disposed between the chassis and the LED drive substrate. The cover includes a lower protrusion cover to enclose a lower protrusion of the clip and fitting protrusion covers disposed at opposing two sides adjacent the upper end of the lower protrusion cover to surround the fitting protrusions of the clip.
