OPTICAL CONTROL MEMBER AND BUILDING COMPONENT MEMBER INCLUDING OPTICAL CONTROL MEMBER

摘要

PROBLEM TO BE SOLVED: To provide an optical control member capable of ensuring visibility in a certain direction even in a light shielding state as well as ensuring the visibility in all directions when no light shielding is required.SOLUTION: The optical control member includes: an optical control layer formed in a pattern including plural first regions 32 and plural second regions 34; and a control layer 40 containing a photochromic dye, which is disposed facing the optical control layer 30 being interposed by a predetermined distance therefrom. The first region 32 has higher optical transmissivity than that of the second region 34.SELECTED DRAWING: Figure 1
