Abstract
An imaging lens assembly has an optical axis, and includes at least one radial reduction lens element and a light blocking element. The radial reduction lens element includes an effective optical portion and a peripheral portion. The effective optical portion includes a reduction part shrinking from a portion of the effective optical portion towards the optical axis so that the effective optical portion is non-circular. The peripheral portion and the reduction part are disposed at interval. The light blocking element includes a receiving structure and an extending light blocking structure. The extending light blocking structure and the receiving structure are disposed at interval, and the extending light blocking structure is connected to the receiving structure so that the effective optical portion is non-circular.
