ILLUMINATOR AND LIQUID CRYSTAL DISPLAY

摘要

An illuminator comprising a plurality of first light reflecting parts (20a) of first V-grooves reflecting light being introduced from a first light source (12a), and a plurality of second light reflecting parts (20b) of second V-grooves reflecting light being introduced from a second light source (12b), wherein the intersectional angle of the face of first V-groove and the intersectional angle of the face of second V-groove are substantially equal at an angle thetap, the face at the plurality of first light reflecting parts and the face at the plurality of second light reflecting parts are inclining at such an angle as the light exits in the direction substantially perpendicular to the longitudinal direction of a linear light guide (14), the plurality of first light reflecting parts are formed at least in a region close to the end part on the side opposite to the side where the first light source of linear light guide is provided and the plurality of second light reflecting parts are formed at least in a region close to the end part on the side opposite to the side where the second light source of linear light guide is provided.
