Abstract:
1. A backlight device that illuminates a transmissive liquid crystal panel from the back side, the backlight device comprising: a plurality of light source substrates on which a plurality of light emitting devices that irradiate illumination light are mounted; 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 mounted on the light source substrates attached to the bottom chassis, the light emitting devices being exposed to one surface side through the openings, the reflector reflecting the illumination light irradiated from the light emitting devices; a diffuser facing the one surface side of the reflector through a predetermined facing interval from the reflector and internally diffusing the illumination light incident from the reflector; 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 transmissive liquid crystal panel, wherein the reflector is directly attached to the one surface of the bottom chassis, and the light source substrates are pushed against the bottom chassis.
