Claim:
1. A photographing optical lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof; a second lens element having negative refractive power; a third lens element with refractive power having an object-side surface and an image-side surface being both aspheric; a fourth lens element with refractive power having an object-side surface and an image-side surface being both aspheric; a fifth lens element with refractive power having an object-side surface and an image-side surface being both aspheric; and a sixth lens element with negative refractive power having an object-side surface and an image-side surface being both aspheric; wherein the photographing optical lens assembly has a total of six lens elements with refractive power, and there is no relative displacement among the lens elements with refractive power, 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 are made of plastic material, a focal length of the photographing optical lens assembly is f, an axial distance between the object-side surface of the first lens element and the image-side surface of the sixth lens element is TD, an axial distance between the image-side surface of the sixth lens element and an image surface is BL, a maximum image height of the photographing optical lens assembly is ImgH, and the following conditions are satisfied:
