Abstract
An imaging lens assembly includes a barrel and a lens assembly, wherein the lens assembly is disposed in the barrel. The barrel has an incident light surface and a barrel cylindrical axis, wherein the incident light surface includes a specular region including at least one specular protrusion region disposed thereon. An angle between a shortest line from an innermost edge to an outermost edge of the specular protrusion region and a normal line to the barrel cylindrical axis is θ.
