Light-shielding film, manufacturing method of light-shielding film, optical element, solid-state imaging element, headlight unit

摘要

The light-shielding film includes a black layer containing a black colorant and an oxygen barrier layer formed on the black layer, the oxygen barrier layer is a single layer made of an inorganic material, and the thickness of the oxygen barrier layer is 10 to 500 nm. The manufacturing method of the light-shielding film includes a step of applying a light-shielding composition containing a black colorant, a resin, a polymerizable compound, and a polymerization initiator on a support, and curing the obtained coating film to form a black layer, and on the black layer. And a step of forming an oxygen barrier layer.
