<p>PROBLEM TO BE SOLVED: To provide an optical control member capable of achieving light shielding control uniform in the whole area.SOLUTION: In an embodiment, an optical control member includes: a base material 12 having a first surface 12a and a second surface 12b opposing to each other, and having light transmissivity; a first light shielding transmission layer 20 provided on the first surface of the base material; a second light shielding transmission layer 30 provided on the second surface of the base material and opposing to the first light shielding transmission layer. The first light shielding transmission layer has a plurality of first regions 20a and a plurality of second region 20b provided in parallel alternately, and each second region has a characteristic of transmitting light more than the first region. The second light shielding transmission layer has a plurality of first regions 30a and a plurality of second regions 30b provided in parallel alternately, and each second region has a characteristic of transmitting light more than the first region. A side-by-side pitch P1 of the plurality of first regions and the plurality of second regions in the first light shielding transmission layer is larger than a side-by-side pitch P2 of the plurality of first regions and the plurality of second regions in the second light shielding transmission layer.</p> |
