Abstract: A backlight device that illuminates a transmissive liquid crystal panel is disclosed. The device includes: a plurality of light source substrates on which a plurality of light emitting devices irradiating illumination light are mounted; drive substrates having drive circuits for the light emitting devices and electrically connected to the light source substrates; a bottom chassis having one surface to which the plurality of light source substrates are attached; a reflector having openings corresponding to the light emitting devices and through which the light emitting devices are exposed, and reflecting the illumination light; a diffuser facing the one surface side of the reflector through a predetermined facing interval and internally diffusing the illumination light; and an optical function sheet laminate combined with the diffuser on one surface side thereof, containing a stack of a plurality of optical function sheets and guiding the illumination light to the liquid crystal panel.
