Document Type and Number:
WIPO Patent Application WO/2008/029831
Kind Code:
A1
Abstract:
It is possible to provide a light receiving element capable of detecting a wavelength change
of a received light by using a simple configuration and to provide an illumination device
capable of appropriately adjusting the color balance by using the light receiving
element and a display device using the illumination device. The light receiving
element (1) detects a light quantity from a plurality of light sources having
different light emission bands. The light receiving element (1) has a plurality
of narrow-band light receiving regions (10R, 10G, 10B) having a sensitivity based
on the respective light emission bands of the light sources and a wide-band light
receiving region (10W) having sensitivity based on the light emission bands
of at least two light sources among the light sources.
