Abstract: An optical imaging lens assembly includes seven lens elements which are, in order from an object side to an image side: a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element. Each of the seven lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The object-side surface of the first lens element is convex in a paraxial region thereof, and at least one surface among the object-side surfaces and the image-side surfaces of the seven lens elements has at least one inflection point.
