1. An optical module, comprising:

a substrate; and

a black matrix arranged on the substrate and a plurality of optical lenses spaced apart from each other,

wherein an orthogonal projection of a gap between adjacent optical lenses onto the substrate is located within an orthogonal projection of the black matrix onto the substrate, and the black matrix is made of molybdenum oxide;

the optical module further comprises an etch stop layer arranged on a side of the optical lens away from the substrate and covering the optical lens, wherein the black matrix is arranged on a side of the etch stop layer away from the substrate.
