LIGHT RECEIVING ELEMENT, AND ILLUMINATION DEVICE AND DISPLAY DEVICE USING THE SAME

摘要

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.
