摘要： A wide-angle optical lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element. The first lens element with negative refractive power has a concave image-side surface. The second lens element with refractive power has a concave object-side surface and a convex image-side surface. The third lens element has positive refractive power. The fourth lens element has positive refractive power. The fifth lens element with refractive power has an object-side surface and an image-side surface which both are aspheric. The sixth lens element with refractive power has a convex object-side surface, wherein the object-side surface and an image-side surface thereof are both aspheric. At least one of the second lens element and the fifth lens element has at least one inflection point.
