Claim:
1. An optical image 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 having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof; a third lens element having positive refractive power; a fourth lens element with negative refractive power having an image-side surface being concave in a paraxial region thereof; a fifth lens element with positive refractive power having an image-side surface being convex in a paraxial region thereof; and a sixth lens element with negative refractive power having an object-side surface being concave in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof, wherein the object-side surface and the image-side surface of the sixth lens element are aspheric, and the image-side surface of the sixth lens element comprises at least one convex shape in an off-axial region thereof; wherein the optical image lens assembly has a total of six lens elements, there is an air space between every two lens elements of the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element and the sixth lens element that are adjacent to each other, an axial distance between the first lens element and the second lens element is T12, an axial distance between the second lens element and the third lens element is T23, a curvature radius of the object-side surface of the sixth lens element is R11, a curvature radius of the image-side surface of the sixth lens element is R12, and the following conditions are satisfied:
