1. A photographing optical lens assembly comprising six lens elements, the six lens elements being, 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;
wherein each 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 has an object-side surface facing towards the object side and an image-side surface facing towards the image side;
wherein the fourth lens element has negative refractive power; the object-side surface of the fifth lens element is concave in a paraxial region thereof; the object-side surface of the sixth lens element is convex in a paraxial region thereof, the image-side surface of the sixth lens element is concave in a paraxial region thereof;
wherein an absolute value of a focal length of the second lens element is greater than an absolute value of a focal length of the third lens element; an absolute value of a focal length of the fourth lens element is greater than an absolute value of a focal length of the sixth lens element; an absolute value of a curvature radius of the object-side surface of the first lens element is greater than an absolute value of a curvature radius of the object-side surface of the sixth lens element;
wherein a focal length of the photographing optical lens assembly is f, a vertical distance between a non-axial critical point on the image-side surface of the sixth lens element and an optical axis is Yc62, and the following condition is satisfied:
