A backlight device in which a reflector can be easily taken in and out and can be efficiently replaced by preventing friction between a casing and the reflector from occurring when the reflector is assembled in the device and variation of optical characteristics after the assembling can be suppressed. In order to provide such a backlight device, the cross sectional shape of the reflector is gradually reduced in its inserting direction.
