Abstract
An imaging lens assembly includes a plurality of optical elements and a lens barrel. At least one optical element of the optical elements is a lens element. The lens element includes an optical effective portion, a peripheral portion, a light-blocking coating layer and a nanostructure layer. The light-blocking coating layer is disposed on at least one surface of the object-side peripheral surface and the image-side peripheral surface and includes a tapered portion. The tapered portion is tapered adjacent to a boundary between the optical effective portion and the peripheral portion. The nanostructure layer is disposed on the optical effective portion and the tapered portion of the light-blocking coating layer, and the nanostructure layer has a plurality of irregular ridge-shaped protrusions. The tapered portion of the light-blocking coating layer forms a light-passing opening adjacent to the boundary along a direction surrounding the optical axis.
