A wide-angle lens assembly comprises sequentially from an object side to an image side along an optical axis a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The first lens is a meniscus lens with negative refractive power. The second lens is a meniscus lens with positive refractive power. The third lens is a biconvex lens with positive refractive power. The fourth lens is with refractive power and includes a convex surface facing an object side. The fifth lens is with refractive power and includes a concave surface facing an image side. The sixth lens is with negative refractive power and includes a concave surface facing the object side.
