Imaging lens assembly, imaging device and vehicle photographing device

An imaging lens assembly comprising, in order from an object side to an image side:

• a first lens element with negative refractive power having an image-side surface being concave in a paraxial region thereof;
• a second lens element with refractive power having an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof;
• a third lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof;
• a fourth lens element having negative refractive power;
• a fifth lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof;
• and
• a sixth lens element with refractive power having an image-side surface being concave in a paraxial region thereof, wherein the image-side surface of the sixth lens element has at least one inflection point in an off-axis region thereof, and both of an object-side surface and the image-side surface of the sixth lens element are aspheric;
• wherein the imaging lens assembly has a total of six lens elements with refractive power, and at least three lens elements among the first through the sixth lens elements of the imaging lens assembly are made of plastic material.
