ABSTRACT:
A light emitting device is provided with an LED substrate (mounting substrate) (12); a plurality of light-emitting diodes (LEDs) (21) mounted on the LED substrate (12); and a reflector (50), which is mounted on the LED substrate (12), has a first surface (52a), and a second surface (52b) having a front-rear relationship with the first surface (52a), reflects light emitted from one light-emitting diode (LED) (21) of the light-emitting diodes (LEDs) (21) by the first surface (52a), and reflects light from the light-emitting diode (LED) (21) adjacent to the one light-emitting diode (LED) (21) by the second surface (52b). Thus, in a backlight device using a solid-state light emitting element, such as a LED, luminance is made uniform by reducing luminance nonuniformity.
