发明名称 LIGHT-GUIDING DEVICE AND DISPLAY APPARATUS
摘要 Difference between light intake quantities just from a front and from an upper direction is reduced in an illuminance sensor. A light-guiding member includes a light-guiding member base part, a compound light-guiding part and an infrared light receiving light-guiding part. Side surface parts each extending backward are formed at right and left ends of the light-guiding member base part. The compound light-guiding part includes a front square column part extending frontward from the light-guiding member base part, a back square column part extending backward therefrom, and a round column part extending frontward from the front square column part. A plurality of slits are formed in the light-guiding member base part such that boundaries of base portions of the front square column part and the back square column part communicate with each other.

主权项 1. A light-guiding device that guides light to an illuminance sensor of a display apparatus, comprising a light-guiding part of a column shape, wherein one surface of the light-guiding part is a light incident surface on which the light is incident and one surface facing thereto is a light emitting surface from which the light is emitted, a first side surface which is one of surfaces orthogonal to the light incident surface and a second side surface facing the first side surface are in parallel, and the first side surface is disposed to be horizontal in a state of being attached to the display apparatus.
