LIGHT-GUIDING DEVICE AND DISPLAY APPARATUS

WIPO Patent Application WO/2014/077347

A1

Provided is a configuration by which the difference between light intake quantities from the front and from the upper direction in an illuminance sensor is reduced. A light-guiding member (50) is integrally formed from a transparent resin material, and is provided with a plate-shaped light-guiding member base part (52), a compound light-guiding part (60) for guiding light to an illuminance sensor (40), and an infrared light receiving light-guiding part (59) for guiding light to an infrared sensor. Side surface parts (53) each extending greatly backward are formed at right and left ends of the light-guiding member base part (52), respectively. The compound light-guiding part (60) is provided with a front square column part (62) extending forward from the light-guiding member base part (52), a back square column part (63) extending backward therefrom, and a round column part (61) extending forward from the front square column part (62). In the light-guiding member base part (52), a plurality of slits (65-67) are formed such that boundaries of base sections of the front square column part (62) and the back square column part (63) communicate with each other.
