Imaging lens assembly module and electronic device

An imaging lens assembly module, comprising:

• an optical lens assembly defining an optical axis;
• and
• a variable aperture module, comprising:
• a plurality of single layer light blocking sheets disposed around a circumferential direction of the optical axis to form a light through hole, a dimension of the light through hole being changeable, each of the single layer light blocking sheets formed by a uniform medium, and having a plurality of particles dispersed in the uniform medium, and each of the single layer light blocking sheets comprising:
• an object-side surface;
• an image-side surface disposed relative to the object-side surface, and being adjacent to an image side of the imaging lens assembly module;
• and
• a light blocking surface connecting the object-side surface and the image-side surface, the light blocking surface extending around the circumferential direction, and the light blocking surface connected to another one of the light blocking surface by observing along a direction of the optical axis;
• wherein, an appearance of the light blocking surface is undulating.
