1. An imaging lens assembly, in order from an object side to an image side, substantially consisting of:
a stop;
a first lens having a positive refractive power, a convex object-side surface and a convex image-side surface;
a second lens having a negative refractive power and a convex and meniscus shaped image-side surface;
a third lens having a negative refractive power, an image-side surface being concave at a paraxial region and being convex and meniscus shaped at a peripheral region, and an object side-surface being concave at the paraxial region; the image-side surface of the third lens having an inflection point; the object-side surface of the third lens has no inflection point;
at least one of the surfaces of three lenses being aspheric, and the imaging lens assembly satisfying following condition:
