PROBLEM TO BE SOLVED: To provide an optical element capable of suppressing at least either aggregation of the protruded patterns or generation of dents in the light absorbing layer during manufacturing steps.SOLUTION: A micro louver 100 includes: a transparent substrate 110; a transparent layer 120 formed on a surface 111 of the transparent substrate 110; a plurality of protruded patterns 130 formed on the transparent layer 120 by being isolated from each other by having an upper face 122 as the top face provided that the surface of the transparent layer 120 in contact with the transparent substrate 110 of the transparent layer 120 is a bottom face 121 and the opposite side thereof 121 is the upper face 122; and a light absorbing layer 140 formed between the protruded patterns 130. Further, regarding the section of the protruded pattern 130 as a face perpendicular to the surface 111 of the transparent substrate 110, a width 132 on the upper face 122 side of is wider than a width 131 on the bottom face 121 side. |
