Imaging lens assembly, imaging device and mobile terminal

摘要

An imaging lens assembly includes, 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, and a sixth lens element. The first lens element with positive refractive power has a convex image-side surface. The second lens element has refractive power. The third lens element has refractive power. The fourth lens element has refractive power. The fifth lens element has negative refractive power. The sixth lens element with negative refractive power has a concave image-side surface in a paraxial region thereof, wherein both of the surfaces thereof are aspheric, and at least one of the surfaces thereof has at least one inflection point. The imaging lens assembly has a total of six lens elements with refractive power.
