Abstract
An imaging lens assembly module has an optical axis, and includes at least one plastic lens element, a carrier element and a light absorbing layer. The plastic lens element, in order from a center to a peripheral region thereof, includes an optical effective portion and a peripheral portion. A side of the peripheral portion includes a plurality of step structures interposed between the side of the peripheral portion and a same side of the optical effective portion. The carrier element defines an inner space for disposing the plastic lens element, and includes a tip end minimal opening and a plurality of annular inner walls. The light absorbing layer is disposed on the peripheral portion of the plastic lens element, and the step structures and the at least one of the annular inner walls facing towards the plastic lens element.
