Title:
LIGHT EMITTING DEVICE AND DISPLAY DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2008/013072
Kind Code:
A1
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 reflecting plate (50), which is mounted on the LED substrate (12), has a first
surface (52a), and a second surface (52b) having 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 LED, luminance is
made uniform by reducing luminance nonuniformity.
