A wide-angle lens assembly comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens sequentially from an object side to an image side along an optical axis. The first lens is a meniscus lens with negative refractive power. The second lens is with negative refractive power and includes a convex surface facing an object side. The third lens is with positive refractive power and includes a convex surface facing the object side. The fourth lens is with positive refractive power and includes a convex surface facing an image side. The fifth lens is with negative refractive power and includes a convex surface facing the image side. The sixth lens is with positive refractive power. The wide-angle lens assembly satisfies Vd4−Vd5≥50, wherein Vd4 is an Abbe number of the fourth lens and Vd5 is an Abbe number of the fifth lens.
